For warning a server about a Ping of Death (PoD) that could have hit it. Apparently when I tried to warn them, one of the admins thought I was trying to get them to PoD their own server. I was unbanned when I explained over a ban appeal that I was warning them about it, not trying to get them to do it. I guess the admin was tired at the time
Also I was banned from a server I was a moderator on because the admin kept going invisible, griefing, going visible again and then blaming me. He unbanned me, explaining that it was a joke. I didn't find it funny
In fact, those are the only two times I have been banned from any Minecraft servers
