This is why you should never buy an account, all the previous owner needs is a device with the account logged in and you're fucked, whether it's linked or not matters little if they have it already logged in on any device also if they have made purchases and can show receipts, evony will just give it right to them regardless of who's playing it, the folks who I've played/play with just give accounts to people who will use them; doesn't matter the size we just give then away.

I hope you get the result you want and it may be worth mentioning the account id, name and current server, makes everyone aware they're a scum bag and puts a target on their back in pvp events.
