        Immediately bans the following things when a new member joins:
        - discord.gg links in name
        - "add me SomeName (tag) 1234"
        - Instant leavers (after 3 offenses)

        Offenders will be banned from all servers AutoLeaf protects, and instant-leavers will be tracked cross-server.
    
        This is not designed to be a permanent solution! This is simply a patch to help slightly alleviate the current issues until Discord gets it figured out.
