[Admins]

Well personally I don't see something wrong if players get banned if they make fun of admins and don't stop after being warned. Of course such situations are not always simple, you might just have fun by doing that, but you must also see that it's hard to manage a server if such stuff is tolerated. It would be best if the manager/staff more give formal warnings before banning or jailing though.
