Game Masters CANNOT:
Commands used by Game Masters are heavily monitored by Admins and other Game Masters. If an odd behavior is noticed, the Game Master breaking the rules will be kicked out and be stripped of their powers, on top of their legit account being banned.
Regular Game Masters have their GM account restricted: they can't deal, send or remove items to/from others in any way. The Lead Game Master has the ability to handle items. They are GMs trusted by the higher-ups. They can only send and remove items if it's strictly necessary (Eg. Oopsy Policy, Items lost through bugs, etc.). Items/Zeny/Premium Points/Limited Premium Points sent or removed are monitored. The Lead has to report every items sent personally to the admins and will be punished if the reports don't match the regularly monitored logs.
