GTC for ISK trading outside official system is NOT SUPPORTED
This message goes out to all those who sell Game Time Codes for ISK. Trading outside the official secure system is risky and may cause you, the sellers, serious problems. The secure system was designed and created in order to ward off the constant problems we have had with ISK sellers, hackers, exploiters and others laundering ISK using GTC trades. If you receive ill gotten ISK for your codes we may be forced to remove the ISK. No compensation will be possible for lost ISK or codes.
