Lets go back to before the token system.
A head upload costs 20000
A body upload costs 10000
Too lazy to farm, have no time, or just tired of the upload you own? refund it for half of what you purchased it for and spend the gralats on something you'll use.
Half of what you earn is losing gralats, there was no conceivable way to profit from refunding your uploads.
In other words, players refund their uploads around events such as christmas. You as staff would notice the spike in refunds, You should know for a fact that is due to an event and someone refunding a large amount of uploads is not someone exploiting a system or however you labelled it.
Please explain this "bug" or continue to defend a ludicrous money grabbing change, it is obvious to anyone who has been playing iclassic or any graal server long enough that the reason this change was implemented was due to refunds being more common then a gralat pack purchase.
