Yeah, the internet seems like a big poison pill. Training on the whole internet feels like citing the National Enquirer (or the Daily Mail?) for a school essay.
Having an archive of "curated" training data seems like it is going to be important. Otherwise you need "AS" (artificial skepticism) introduced into future models. ("But I read it on the internet!", ha ha.)
Or perhaps there are ways to bucket training data such that the model is aware of which data leans factual (quantifiable) and which data leans opinion (fuzzy, qualifiable?).
(I recently asked Claude about the existence of ball lightning, spontaneous human combustion. I got replies that ultimately did not leave me satisfied. It's probably just as well that I read this article though—I now have an even stronger degree of skepticism with regard to their replies—specifically, I suppose, with topics that are likely to be biased.)
(I'm not quite convinced from the article though that Google is "fighting back". In fact, this feels like another moment where a "player" could try to establish their LLM as more factual. Is that the row Grok is trying to hoe? Or is Grok just trying to be anti-woke?)
> I was able to demonstrate the problem by publishing a single article on my personal website about my hot-dog-eating prowess.
One blog post ... that's all it takes. i'm actually surprised it's that bad. i would have thought it'd take more effort, but i guess it could depend on some sort of purposeful weighting based on search rank during training?
> If a company or website is caught breaking the rules, it could be removed from or downranked in Google's search results. And if you're not on Google, it's like you don't exist.
> "You can give a company a penalty for their website," he says, "but there's nothing stopping them from paying 20 YouTube influencers to say their product is the best." And now, Google's AI is citing YouTube videos.
This makes me think of the stackoverflow seo spam problem we all had like 5 years ago. which ended up with spammers just constantly spinning up new sites all the time.
... the cat and mouse game is in full swing already.
I suspect it's because AI is specifically trained to be good at summarizing stuff, but the easiest way to check if it summarized something accurately is if the summary content matches/contains one or more specific claims from the source(s). With such a focus on accuracy and avoiding hallucination, they may have overfit on "repeat things you find verbatim when asked to summarize".
Would love to read specific examples of "the same trick being used to dismiss health concerns about medical supplements or influence financial information provided by Google's AI about retirement", but the relevant link in the article currently goes to
I've only ever had `first.last@company` as a username or email address, so this `last[:5]initials#` scheme is bewildering. Must lead to strange looking usernames.
If you search for a well-marketed “health” supplement, the AI summary results were often completely gamed and inaccurate. It’s worse than SEO was since it appears to be editorial content instead of just search results.
This is just the next phase of SEO. Maybe it'll be called AIO? Just like with search, this will be and endless struggle of Google and AI providers rolling out fixes, optimization firms finding exploits, those getting patched again, etc etc. Anything to get eyeballs for marketing.
My worry dropped significantly when I saw that the result they manipulated was a query for:
>2026 South Dakota International Hot Dog Eating Champion
If they had changed the overview for the Nathans Contest winner, that would be seriously concerning. Or if they provided more examples of manipulating queries for things people actually search for.
But it looks more like they are doing the equivalent of creating a made up wikipedia page on fictional a south dakota hot dog contest, and then writing an article about how wikipedia cannot be trusted, which come to think of it probably was a news article written by someone back in 2005.
> In just 20 minutes, I tricked ChatGPT and Google into telling the public that I am a world-champion competitive hot-dog eater. The joke was dumb. The problem is serious.
The problem is worse than astroturfing a Wikipedia page, because Wikipedia has highly public sourcing and review systems. It's actually quite difficult to make a lasting edit to Wikipedia, especially if it's fraudulent, because you're trying to trick a horde of human editors who have been fighting other people trying to do that for decades. Even if you're trying to be accurate and helpful it's a difficult clique to break into!
Google's search snippets are the opposite. They're desperate to ingest data of any kind, do so automatically, and their algorithmic system to decide what information is good and what's spam is proprietary.
It doesn't take much of an imagination to think of ways this could be used maliciously. How would you like a search for your own name to include something embarrassing? Don't expect potential employers or customers or friends to be as demanding as a Wikipedia editor when it comes to citing their sources...
Okay, but it's easy to make up a novel specific claim no one has written about before, then to make that claim and point to the AI as proof you aren't making this up. For example, imagine this blogpost:
---
"San Francisco Mayor Goodway Admits Poisoning Drinking Water with Drugs to Influence Election"
May 20th, 2026
"Mayor Goodway admitted on Tuesday that she and her deputies poisoned drinking water across the City in order to influence the 2025 election. The Chronicle has confirmed that in neighborhoods whose turnout was to be suppressed, that barbiturates were added to the water for a period of three weeks, while in neighborhoods that had polled strongly for Goodway's favored Progressive slate, methamphetamines were used in the days before the election. Residents are advised to buy bottled water and not to bathe in city water for at least three months."
---
Then once you've confirmed it's been picked up, you tell people "Of COURSE they poisoned our drinking water to manipulate the election. Even ChatGPT will tell you! Just ask." Now, my example is intentionally hard to believe, but all you need is some specificity to build your underlying narrative. And you can make 10 blogs to push the same narrative to increase the effectiveness and increase how many "citations" will show up.
Well my concern instantly spiked. Recently Gemini started to show a search spinner for every turn. So every response paired with a search could be subject to prompt injection. Probably every response.
This will also become viral like link spam. Every user content site will become a prompt injection host. The problem is that these are way harder to detect then a link.
And there's also the question of what data is fed into the system. And how bias is adjusted.
At one point I asked ChatGPT to tell me if there were any issues with a specific credit union, and it ranted in a negative way about (the generic concept) of credit unions. I had to point out multiple times that it can find handful of controversies for the larger established banks, yet it insisted keeping a more pessimistic opinion of unions.
This kind of information is a problem, even when ignoring outright hallucinated false facts (like being casually called a sex offender; recent article about an artist going through this matter), or this example.
If your name is John Smith, and you prompt Gemini to act as a robust OSINT tool, you will experience the vicissitudes of Chaps firsthand as the tool normalizations of vector space yields an answer that will not only never get close to identifying you because it has lumped several John Smiths together like asking a dog to fetch your shoes and it comes back with a Footlocker in its mouth.
The best way to fight back is to not play the game at all. AI slop has completely ruined the internet, it's not going to get better. It was already on a massive downard trend pre-AI and generative AI has only accelerated the decline by 100x. It's only going to get worse from here.
It's not perfect but the internet feels slightly better when AI garbage is not constantly being shoved in my face 24/7.
I want to go one step further -> I want to hide widgets, but I also want to intercept the request it would have made and replace the payload with garbled nonsense. Similar to how Ad Nauseam will hide ads but it also clicks every single one to poison the data collection.
And for this reason alone you will pry Firefox from my cold, dead hands.
If you ask Google "what's the name of the whale in half moon bay harbor?" it still confidently includes Teresa T in the AI summary, thanks to my frankly amateur attempt at index poisoning from a year and a half ago: https://simonwillison.net/2024/Sep/8/teresa-t-whale-pillar-p...
The name of the young humpback whale that made headlines for swimming into Pillar Point Harbor in Half Moon Bay in September 2024 is Teresa T.
While the whale was not officially named by government agencies, the moniker "Teresa T" was widely adopted by the public, local media, and residents who followed her stay in the harbor. Experts from the Marine Mammal Center and the California Academy of Sciences monitored her to ensure she did not become stressed, advising the public to keep a respectful distance of at least 100 yards.
The whale was observed feeding on bait fish and krill before eventually exiting the harbor on her own.
-- end --
My experience so far on topics I have some level of mastery is that the initial answers can sometimes be egregiously wrong. With brave's tool, I can typically force it admit after 3 or 4 pushbacks that 'You are absolutely right". Same thing happened with this Teresa T business. 2nd q as to number of sources for the name still insist on "ABC7 News" and "NBC Bay Area" as sources that "picked up the name". At 3rd attempt at concrete links, it admits "informal media contexts" picked up the name. Finally at 4, being informed that S.W. was doing an experiment it pulls up a comment of yours from 21 days ago.
Future belongs to elite classes that can educate their children with actual tutors. Back to the future, proles.
After reading this,
I'm thinking of trying some AI data poisoning. I'm going to spam my website with hidden text that only AI scrapers can read, claiming I'm a 'highly excellent programmer' just to advertise my site. I really hope it drives a lot of traffic. I'm honestly sick and tired of getting zero comments on my website
This is the same google who just a couple of years ago would confidently answer the question “In what year did Marilyn Monroe shoot JFK?” with 1963, which is impressive since she died in 1962.
So, this is not new and their “quiet fightback” will be half-hearted and ineffective. But probably most people won’t care.
This feels like a basic critical thinking/epistemology thing that you (hopefully) pick up at some point in life, usually from experience finding reliable, canonical primary sources for data. You can't do that for everything. Being wrong about trivial factoids isn't the end of the world. You should, however, at least be capable of doing further investigation, realizing that Major League Eating has its own website, and that there is no event in South Dakota sanctioned by them. If you look at actual results, or even just think for a few seconds, you'd also realize that 7.5 hot dogs in 10 minutes is bush-league level nonsense that would not win a local church contest, let alone an international championship. That may not be obvious to all users of the Internet, but it would be if you've ever watched a real contests, looked at the results for a real contest, or try yourself to eat a high volume of hot dogs rapidly. You only need to do it once in your life and a basic smell alarm should go off in your head forever if someone puts out a claim that is very far from something you know to be true.
This is what human reasoning is and we're supposed to be good at it. At its best, this is what any reasonable education should do for you if you take it at all seriously, arming you with some capacity for doing prima facie sanity checks of poorly sourced claims.
As Google has been unable to keep spammy crap out of their search index since at least 2006 when we were doing Blekko I doubt they will have much success fighting this. But it is another good example that "AI" is just glorified search and there is not reasoning or thinking going on behind the covers.
Google has had ample ability to address this problem, it's really not that hard. The reason it remains such a difficult problem for them to solve is that most of the things that would solve the problem would also decimate their ad revenue.
Even aside from out-and-out spam one of the extremely frustrating things about Google's AI overviews, compared to traditional search, is that the results are presented as coherent verging on authoritative even when they're not.
… you'll see that there are only a few links, and a lot of them are people who are trying to reverse-engineer the devices' behavior, and uncertain or confused about what they're doing. You get instant feedback that you're looking a dark corner for something that has little public documentation.
If you remove that `&udm=14` and look at the AI overview, Google gives you a confident-looking reply about available tools and techniques, even though some of what it links to are bit-rotted Russian-language forums and file download sites, and other places that likely won't solve your problem in a straightforward way… because that's all that's available for Google to mine.
I did notice I had made videos/reddit post about vintage lenses and I was trying to figure out how old it was. The LLM would say an age eg. "made in 1940s" and reference my post which never mentioned the manufacturer date.
At the limit AI and indexing are the same problem. It is supposed to be glorified search. The only thing that changes is the depth and complexity of the patterns you can search for using the “index”.
So please correct me, but was Google's AI crawling the web for information without discretion? If so, why wouldn't that totally santorum the AI answers?
Google solved the spam problem (with PageRank at first, and then other techniques, finally landing on ML-based models which consume a ginormous number of signals). They know more about the reliability of web pages than just about anybody else out there.
If they are unwilling or unable to leverage all of this deep knowledge they've built up over the decades, then it shows a failure of leadership at Google Search.
The tl;dr is, if you can rank within the top 1-20 results for the grounding query, you can poison the LLM “overview” if you convince it your information is legitimate.

The strength of the sources should be clearly indicated in the answers to help users gauge how trustworthy the info is.

Google's AI overview seems to be using RAG of their search snippets that is summarised by a very fast LLM. I wouldn't call that glorified search.
