The first one can't spell.
The second one has pretty teeth. He should change his main photo to the smiling-with-teeth photo.
The third one drinks a lot.
The fourth one really needs to work on his profile and take a happier picture.
I like the fifth one. He has personality.
The sixth one needs to not advertise that he has never read a book he liked.
The seventh one made a lot of points in his first paragraph, but I would remove the third all together. It makes him look a bit stuck on himself.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
