The problem with this is, any appeal would only happen after the banned person does their time. Not quite right. I really think having a copy of the original post in a read-only thread is good. If someone is banned, let everyone see why.

I'd even go as far as to have the moderator move the post to a locked read-only thread, and replace the post with a notice that the person was banned for the post, how long they were banned, and a link off to the post for those who want to see why. That allows everyone who wants to the ability to see why they were banned, and those who don't can skip in. It would also put a very clear indicator of what's acceptable and what's not, and that there's a consequence for breaking forum rules and using abusive language and slander.

Ah, but if the post is still around to read, then it's not really "alleged" any more, is it?

And as has been noted several times, Council is always an option. It has been, and continues to be.

That is, unless you think everyone on Council is conspiring against you in a scheme to... take over the world?

PS: Look at me... I pulled it off! I have all the power! With my position on... Wait. What power do I have here? Right... None. Never mind.
