I'm sure Gmods and Game admins are bored of some of the bad apples in the community. Some of them are just flaming but some takes it a little further than this. The thing is these members don't mind to be muted for a week or two they rarely get +100 even if they do some choose to create a double account to have more fun. Usually the second (or more) account gets permabanned but the main account remains unharmed and after the mute they go back to their usual cursing in the game, teamkilling or flaming in the forum.
Obviously the usual warnings or 3 days of bans are not effective enough. How about :
Warning the player then in case of repeating the same (can be traced from moderation log) action forcing to account to pay a fixed fee of 100K or two (or more) part tariff of 50Kx2, 25Kx4 etc.
In case of transferring all the gold to an another account then misbehaving : both accounts will be charged.
I believe this would seriously discourage the players to misbehave and reduce the amount of bad apples in the community. This is a rough idea about the system.
Cheers.
