Such is forum life!
But seriously...have you tried to resolve the problem directly, with the person/people with whom you have an issue?
I'm not fully au fait with the background to your dispute, but if things have been said which you both (in hindsight) regret, one of you may have to be big enough to get in touch and try and smooth things over.
Otherwise...find other forums like this one.
Don't worry about the ban. Just move on.
