I never offered sex.
I still got some strange PMs though.
My daughter got one from a user name "lonelyman88". Gave out his email and all other sorts of contact info. The name alone raised a red flag in my mind. Amber never went back to wp after that.
Looked him up and he was a 16 year old male (don't know when he sent your daughter the PM). I don't know if he was aware of your daughter's age. Profiles didn't have ages stated in them back then. Now they do but only by the member's choice.
Since his first post is dated from 2004, that make him 20 now if he has had a birthday yet.
Interesting thing is he sounded desperate for friends and I saw a post by him asking what does he need to do to get laid and he was real desperate for a girl.
