Why Am I Seeing Inapropriate Ad's on Facebook, Youtube, and other common sites?

It's not a virus. That's just how the World Wide Web is. I see that `Facebook of Sex` advertisement that you're talking about here on Yahoo! Answers sometimes.

And yes, those sites are being paid to have those advertisements placed there.

For me, I think it's probably because I visit quite a few piracy-related forums. They assume pirates and amoral people such as myself are more likely to visit those sites, I suppose.

You could always use a pop-up blocker if you don't want your children to see those advertisements.
