I admit it sounded good at first but there are way too many "Backdoors" in the fining system for the admins and coders to cover. Even my suggestion has flaws like people porting the jailed out (though the party command could be restricted) there will be people who manage to find a way to exploit any punishment system, however when you are banned, you can't exploit it unless you deliberately make alt accounts and proxy IP's.
Whats worse is that you cannot have a percent NOR a set fine for each crime, Because set fines may be little money for rich people, and a percentage means that you will always be able to pay the fine... come on, 0.25c x 0.25 = 0.06 then 0.06 x 0.25 = 0.015 <-- which again can't be done because the currency is fixated to 2 decimals.
But I seriously like my cage idea. If that were implemented, public humiliation may be fun.
AND they can't play
