A thing about Passwords is a situation like this:
M1 creates a vanilla room and adds the password. M1 invites a bunch of his friends and gives them the pw to join
M2 invites M3.M1 does not like M3 and same with M3. Conflict happens, and since M3 is friends with the other mice,
They will not voteban M3, And theres mostlikely not gonna be enough mice to vote ban.
