Are you referring to the targeted ads above and below the thread? I think those are unique to the individual, based on your search history. For example, I see ads for autoerotic asphyxiation support groups and clown/party supplies. The clown stuff is for work, though.
I have no problem with ads in lieu of paying a fee, bit the ones that are targeted to us seem kind of scary and I have no interest in clicking on them.
I see an ad for a repossession company... I take that as foreshadowing that somebody is due to rip me off.
I also see two ads for 400***BAD***400 which I'm guessing might be an ad for a new film, that is a cross between the greek odyssey 300, and boyz in the hood.
