I found this in my Nginx logs, they teached marketing to all of us

I was earlier today reviewing some logs from one of my Nginx instances and found the following entry:

``` 401 GET / Expanse, a Palo Alto Networks company, searches across the global IPv4 space multiple times per day to identify customers' presences on the Internet. If you would like to be excluded from our scans, please send IP addresses/domains to: scaninfo@paloaltonetworks.com ```

I think it is just genius. It is a demonstration of effective marketing and knowing where your audience is.
