The result of the last meso exploit (RIP lMira)

The tax on buying from a shop is lower than the tax on traded meso.
Therefore, when people want to transfer large sums of meso, the receiver sets up a shop with some cheap common item (such as arrows, white potions, pet food, etc) for sale for the amount they want to receive. The sender buys up the item, thus transferring the meso at the lesser tax rate. (People with extra patience will split the sum, so for example instead of 1 arrow for 100m they're selling 100 arrows for 999,999 each. If the buyer buys them separately, the tax on each purchase is even lower. But I digress).

When it comes to trading in sums that are higher than max meso (which is 10b right now), there is no other choice. If you want to sell a sword for 30b meso, you have to set up shop 3 times and sell rubbish at least twice and the sword on the third (or sell rubbish 3 times and then trade the sword, same thing really).

Nexon observed that Mira sold arrows for billions of meso, which came from an exploit. This raised their suspicion that she was cooperating with the exploiters (or that she owned both accounts and was transfering funds between them). They could have looked at her ticket and gone looking for the transaction of the sword transfer, but they're too lazy.

Thanks. I got confused for a sec...

Also helpful to other particular readers who could potentially help Mira out....

Nowadays I think I'll never value mesos the same anymore. Too risky to use as a currency...
