Which you are mistaken about...
I'm afraid that it's his word against mine.
However, I'm rather sure that the multiple cases of harassment and excessive profanity it is the words of the community against his.
He was never really kind to others, as well, he has been reported by people many times, and I've been told he received many warnings. I tried to be nice, but I never got that in return. Others can say the same about him. In Fact, although is not against the rules but is very rude, he randomly kills people just because they have pvp on. Need proof that he does that for that reason, here.
He clearly does not want to play alongside with others on the server and if he does get unbanned, he really needs to change that. I do believe people can change, I have changed a lot in my time, but for him to change, it will take a lot.
