It's nice to see the news on the launcher about how you folks at Square Enix are taking action against accounts involved in RMT and that the action you are taking is banning them. The problem is that, particularly of late, the are more and more RMT spammers in the game. Some, like gkplayer.com, are changing the character they spam with as often as every 15 minutes.
If this keeps up, we won't have the time to delete old names from our Blacklists to make room for the new ones.
Clearly, your strategy of banning accounts is a failure, despite your intentions. I'm not going to take the cynical stance of suggesting that you're making good money off RMT traders whose accounts you ban over and over. If this game has 1.8 million subs, then the revenue generated for you by RMT accounts is minimal.
The only way you're going to make any headway is to start banning the IP addresses of those banned accounts, the same addresses that are being used over and over by these nuisances.
