Not only do I agree with OP, but I recently posted much the same idea in another thread:
I know this isn't the thread to discuss it in, but I really wish there was something that could be done so that we don't have this many appeal threads cluttering up Meta. At this point it's gotten to be at least as bad as the number of account recovery threads. Would a child board require another moderator?
It was a bit off-topic in that thread, so I'm glad OP started a new one for the suggestion.
Most of these ban appeal threads are much the same--same excuses, same lies, same reasons for getting banned, same replies from members, and the same outcomes. If you're looking for decent threads in Meta, the ban appeal ones are just clutter. I'm not sure if a child board would require another moderator or not, but at least if you're sick of people appealing their bans you can put the child board on ignore.
There's another solution, which is to require all appeals to be done via e-mail and not in a Meta thread. The threads seem to be useless anyway; I think I've seen only one of them in the past few months where a person was erroneously banned, and it got reversed--and I'm sure that could have gotten resolved via e-mail.
