Ask HN: What types of adds do you see?

I was using a computer that wasn't mine recently. I saw adds that was, to a degree, catered towards me (a student). Then I reformatted this laptop and another family members laptop, installed linux and changed some setting in the browsers. (because the computers had problems and I don't have any windows keys to install legit versions). Now, I get adds for "small business owner" or "startups". From Internet companies, hosting companies and other businesses that caters to them. So, I am just curious as to what type of adds HN sees. Thanks.
