If you are really active and correct on the forums, as well as showing a mature attitude you will get Forum Mod, which usually leads to Player Moderator.
To be honest, there was a time I desperately wanted to be a Mod. I think that has waned a lot though.
Another thing to note is not just blindly report every single act of abuse you see in game. Sometimes its better to tell the person (in a nice way) that people might be offended by that and just move on.
