I have a Facebook nemesis. His name is David and he's a geeky little guy who's trolling my account.

David has "friended" all my female friends, and then hits on all of them -- ALL OF THEM.

He's not even funny the way he goes about, it's just kind of stupid.

It's driving me FREAKING CRAZY!

SO MANY women have asked me, "Who is this David?"

And I don't even know him! He's just a Facebook acquaintance!

He irritates the crap out of me. I need him to go away.

Ideas?
