i think google pays people to read forums post and clasify people by them

Google remembers what you searched for and then targets you with related ads.

It's that simple. No conspiracy or teams of people looking through your posts.

It's why Google is valued (money wise) so highly. It's a precise marketing tool.

When you make a search on Google, your ip address, the time, and what you searched for is stored in their database and this information can be used in a court of law.

So if you've been googling then google know.
