I apologize if this has already been suggested.
I don't read Meta very much, but when I do I notice that there are always several current ban appeal threads, as well as threads with users asking why their posts are deleted. Perhaps it would be helpful if there were a board focused specifically on actions by moderators and appeals by users. Moderators could post who was banned and why, and users could appeal their bans there and ask why posts are deleted.
This is probably a good way to keep the discussion in the meta clean and only up to the development of the forum. This will also save the time for moderation to sort out the list of banned appeal's in meta as you will get all of those in one place which makes it easy to handle. Meta should totally be based on the conversation related to development of the forum and suggestions related to it.
Also, as per the rules, a banned account could only post in meta with its alt for ban appeals and nowhere outside it else it's a ban evasion. We could apply just similar rules to the new banned account sub board section which will keep all the conversation in one sub-board and easy to access to mod and also for normal users.
This suggestion is already discussed here, but as per I see, global mods do not find it much important though.
5 out of 35 isn't a lot and I don't think every separate issue needs its own sub.
