theres this guy called minecrapper2001 and he's being really disgusting to me. what do i do?

Depends on what he's doing.
If he's harrassing you, and being a bully, then report him.
If he's just sorta teasing, just in a way that hurts you, ask him to stop. If he doesn't, report him.
Hope that helps.

Block him/ disfan him

report him, ignore him.ask him to stop. don't talk to him. If something serious happens maybe contact Fanpop or possible the police if it's that bad ... hope I was any help

Block and ignore.
Reporting doesn't do anything because I have been reported 3 times and nothing happened.

Is he jsut pulling your leg, or is he actually being a douche? If he is, ask him to stop. If he doesn't stop, report him. There's really nothing more you can do.

I try contacting the Fanpop Four so many times to do something about this, but they won't do anything...

report him

Just ignore him and don't get on fan pop a lot. If that doesn't work, then contact fan pop faculty or don't come on anymore if it gets worse.
