I've never had ban rights, anywhere (with the exception of the servers that have given me local rights, but I don't really count those as I don't use them).

In my opinion, when you ban someone you are removing them from the community. If you remove them from the community, they shouldn't come back to the community unless they are serious about changing.

I might let them come back after, I don't know, 5-6 months if they asked. But I'd ban them if they did something serious again, and not let them come back.
