My eldest niece is 14, she is my SIL's step daughter.

I am friends with her on FB and she posted a status of a silly song that my 6yo niece learnt at school and me and my other SIL were laughing and joking about how we used to skip to it. When one of her friends commented: "wtf r u all on or lack of?" and i replied with "oh yes because we would have to be on drugs to think this CHILDRENS song is funny" and he wrote back that "yes we would lol" so i called him an idiot. It then went back and fourth with silly insults and then he wrote this: well now i cant lie its against my code i can tell u that for every 10 years u age its like its only been 1 year to me im older then u and i can tell that i would be taller faster and stronger than u to u are nothing more than a bag of meat a walking meal ticket my kind is the top of the food chain and u are at the bottom of it by now DP had stepped in and laughed at him and this guy called us "pathetic humans".

I looked at his profile thinking hes 14/15 just like my niece and hes 18-19.. and is ringing big alarm bells.

I want to contact her dad and my SIL but i know they will only punish her when i think this guy is i guess "pretending" to be a vampire to lure in twilight fans and my niece happens to be a HUGE fan. While me and you can look at what hes saying and know hes full of it but to a vulnerable 14 yr old it could be true to them.

I have seen some terrible things on the news this year regarding guys luring girls and hurting them.

The name he has is Raven Williams but DP has found his real profile and by his photos he looks really dodgy. I have this awful feeling in my stomach but i dont know how to deal with this situation. And this guy Mike (is what his name appears to be) has befriended alot of my nieces friends..
