What can I do about this creep?

He's just sick in the head! He must like the attention you give him even if it negative.You have blocked him on P&S now block him from your 360 too.Don't leave yahoo or he wins.Open your comments on your 360.He won't be able to leave comments on your 360 if you block him. He's a stalker. A very sick one at that. If you need support just contact me! I have some lovely contacts that won't stand for his behaviour. ♥
