OP, solid idea. Players that buy gold and gold buying apologist are the only ones against the idea of cheaters being heavily penalized. If you want people to follow the rules and not purchase gold, one of the best ways of doing that is to send a clear message that they will lose their account if they do.
I have zero sympathy for players feed the bot machine. They know what they’re doing is wrong, and how it negatively affects the game we love. If they want to swipe mommy’s CC to gain an advantage, go do it in another game that’s not this one.
