How can I remove the "Facebook of Sex" ad from my Facebook ?

[court]

This is definitely not a Facebook-approved advertisement. If it is being delivered directly through Facebook.com, then you should report the ad--there should be a link to report it, or you can click the "thumbs down". But there is no way to remove it directly from Facebook.com by yourself.

There is a chance that your computer has adware or spyware on it, either from something you downloaded previously from the internet, or as the result of a virus.

Side note: In researching the answer to this question, I found a really funny article about why Facebook for hooking up could never work at http://www.pointsincase.com/columns/case...ook-of-sex
