Givecash, Bounty and Bank are all easily exploited.
A starflier docks with it's rules commodity and after editing the sell price, sells it for 1 billion. That starflier can use the givecash,bounty or bank command to transfer the cash to another character or account. While the server might detect this and kick the starflier when it undocks, taking away all the money it made and giving it back the commodity, the other characters will have the cash OR the starflier will have the cash it transfered. Odd how it works like that but it does.
Yes the server might detect this and the admins consequently ban the characters involved but that starflier could transfer cash to other characters manually etc and so break the papertrail as such. (Save for the logs showing some characters increasing in cash, which could be planned with a merc event next to it so to disguise it)
