The result of the last meso exploit (RIP lMira)

to be completely fair i can absolutely understand why they'd ban based on just that trade regardless of context

people who buy mesos from sites put shops up with arrows in em to get the dosh.

it looks suspicious as hell in the logs.

Of course, and it's quite reasonable to ban someone who receives 20 billion in hacked mesos in return for arrows while you investigate. But the GMs should (might not) be able to see the account's got a legitimate history of large-meso transactions outside the timeframe of the meso exploit.

I've paid for things 999999 at a time using arrows on occasion, it's not that unusual to want to avoid the taxes. Or to transfer more than the meso cap because some items are just worth that much.
