This topic has been brought up time and again. I do understand the frustration here and fully agree with you. However, in reality, it's a lot harder than "just banning them".
Gold spammers, for the most part, are bots controlled by computers that are made to find ways to bypass security systems in games to only make more accounts to spam with. They can do this within a matter of moments and even with every precaution and banning that is done to prevent them, there will never be a resolute way to completely rid the game of them because they always will find a way around each precaution and make more accounts. That's just how bots work.
This fact is just because it is a F2P game and therefore expectantly comes with the territory unfortunately. Even if Aeria banned every one in the game, you'll just have just as many the next day.
