Add a way for servers to bypass the bans and on the game so mojang can’t do anything and hide the warnings or allow people to report anyways so mojang gets a ton of banned people reported

i don't think thats is possible because mojang well simply tells the server thats the account is unauthenticated like a cracked game

hide the warnings is something that can be done and has already been done

Ok

Make the server check for can and override with the offline mode for that player

There is no simple way to implement this, and less simple ways are out of scope for this project. I would want it to remain focused on providing preventive measures.
