How to deal with GOLD SELLER's when ToS is F2P?

[chrono.torment]

Gold sellers will buy with cloned credit cards and a refund will be issued when its owner realizes the purchase(s). By the time a refund is issued, their bots would already have accomplished their purpose.

Mh i am not sure how this should work with the steam credit card verfication system.

even if they cloned credit cards that would still lessen the bots compared to f2p, been telling everyone let this game stay b2p
