To be honest, I was playing at the server today and "Sober-Guy", "CLUBBER" and "LatviaNNNN..." were insulting each other. I warned them, I wanted to ban them, but then I realized that they were just joking around and having fun. What I'm trying to say is that some admins are tolerant and some are not. If not for my patience and the fact that I didn't want to be rude and ban you without warning first, I wouldn't have had enough time to realize that you guys were joking.
Therefore, I would suggest that you don't joke by insulting other players and don't accept jokes of this kind while playing at the server because as I said, not all admins are tolerant and you will end up getting banned again and again.However, since your ban expired yesterday, I don't think you deserve to be permanently banned and should be unbanned.
Good luck.
