Online dating profiles seem to be troll-bait. There's a story in the news about those:

Comedian creates ?worst online dating profile ever? as social experiment - NY Daily News

The author of the profile used her friend's picture and put up the absolute worst possible profile she could imagine. And guys FLOCKED to it because of the pretty girl in picture. Long story short, I guess an online profile is like fishing; you have wade through a ton of carp just to get one darn bluegill.
