I've seen several accounts linked to people in that circle that could possibly be Raven (or Raven's girlfriend(s)). Unfortunately, if Raven's on, I'm betting that he's either got some bogus name, gender, date of birth, etc., to throw people off or he has his profile set to private. The bottom line for me is that if he's still participating on myspace but has altered his profile to the degree that we can't find him with certainty, then he can't possibly be enjoying it like he used to. Not much of a bright side but it's something.
Oh, and btw, I don't know if I clicked an old link but when I went to Shiloh's myspace about a week ago, the picture of her and the baby was gone, and it was back to a pic of her with a short shaggy hair cut, driving a car I think.
