I've already explained my point of view Suchmoon, and I think it is pretty clear. If this kind of "appeals" are allowed, there is no reason to not allow the accused to be able to defend himself against it.
Yes, there is a very simple reason. If you're banned you're not allowed to make posts or send PMs, and there is only one exception to that.
It's an universal democratic principle. Even in North Korea people are allowed to defend themselves, at least in theory.
You say he could defend himself after his 7 days ban, but the "appeal" could also be made after this 7 days...(I'm not talking about random newbie/brand new members here -he's legendary-)
By that logic should everyone be allowed to defend themselves when their post is reported before mods make a decision on it? What does this have to do with being a Legendary?
Mods make a decision. The perp can then appeal if they think the decision is wrong. In this case Danydee already has a ban appeal thread so he surely knows the process and there is no excuse for ban evasion.
