How to restrict a moderator so that he can only ban a user in mod-cp. All other functions can be disable for him, and he can only ban 3 users a day. And can't ban any admin / team member
Well, automatically they can't ban anyone higher than them.
You'd need a plugin for the rest, I believe.
Do it this way... make him an admin, change his admin permissions to only be able to ban users. I think that'd work...
I don't think you can limit the amount of bans per day though.
