Olympus doesn't care about you selling/buying money... Olympus is FORCED to care through Bohemia because Bohemia has some of the fuckiest community guidelines/rules out there and expect the communities to police stuff like this where in reality we shouldn't have to deal with it.

If Bohemia gets wind of it, they'll firstly shut off BattleEye which will kick everyone and lock the servers essentially. Sure, devs could pull off BattleEye and run the servers, but you'd then have every 12-year-old with a script bitch slapping the server.. Oly would put in an appeal, which would get BattleEye turned on 'while they investigate'. During that time, donations would not be allowed. If Bohemia found Oly guilty of not taking action on someone selling money then Bohemia would remove Olympus's rights for monetization (meaning no donations) If Olympus doesn't comply @Ryan would get slapped with a cease and desist request from Bohemia and bye bye Oly.

So, as I said, Oly doesn't give a shit if you sell your in game money for real money (never has), but since Bohemia will have an aneurysm if staff doesn't do something about it they're forced to act.

Tldr exactly what @MAV said. Servers got pulled and shut off on more then one occasion. Not gonna take that risk again. If you are selling and/or buying money and we catch you then you are getting slapped.

runs are the most boring thing in the world
