I get friend requests like this on a regular, almost daily basis.  I noticed this trend last year.  But it seems to be getting worse lately.  I know one of Facebook's biggest challenges is dealing with stuff like this as these pages surely contain links to sites with viruses, malware, spam you name it--which you can quickly spread to others.

Usually the images are not quite so pronographic, typically a provocative bathroon mirror selfie, but sometimes the images are FAR worse (or better depending upon your predictions).

This is the the kind of photo that gets a site banned from Google, but Facebook is strong enough in that they don't have to worry about what Google thinks.

After you accepted the request what happened? lol

I send her some book recommendations and my latest Black History Month post and was unfriended 

lol!!
