Any good ideas for payback ?

[Kreain]

Ok, since my account with Kreain on it was stolen yet again by my friend, first thing is he lied and lied all other times too and wouldn't tell me the email so I couldn't change my account email back and change password, second he denies it was him and I just called him and he said "why come into school and accuse me for something I didn't do" in which then I said "I didn't call to get mad, and I have full proof it was you" *he hangs up*, third now Outspark wont give my account back because it was sharing accoutn which was against ToS which I was forced to share.

so now I am really pissed off and need ideas to get payback..
