This is a good initiative but you need more details about a formal process to be removed from the blacklist.

That is what the proposal is for. If it gets funded, I will establish and execute on it.

There has always been a rights to appeal and I actually have removed people, I just don't post about it. Currently though I did take down the BuildAWhale discord (which is where most things happened) as it has been long enough time it has been decommissioned.

Also, moving forward all blacklists and mute lists will be optional so people can choose to use what they trust, or nothing.
(When this is fully ready and tested, I will post on how to use it).
