I think that if game developers really wanted to stop gold sellers then they would have gone down the legal route by now.
It is probably on their "to-do list" but I don't think it's as high as some of us would want it to be. It is not ruiining my game but it is making it a less fun place to be.
I'd rather they actually wen't to the route of the problem and even if it's difficult, I'm sure it's still possible for them to persue them legally. Attack the websites and not the individual accounts in the game.
There should be a filter where if you spam something repeatedly within 5-40 sec, your reply in chat will be automatically filtered into something like this *****spamming*****. That's what happens in POTCO and it helps a lot.
For some people wondering why are there gold farmer selling wow gold on star trek it's because china government general administration of press and publication has placed a ban on for any one to play wow in china. As you can see since china was about 4million subs on wow most of the gold farmers ran off to other mmos to make money so which why you can see an endless supply of gold farmers on star trek.
In shorter terms blame china's government for making this game crappier and for once not having to blame the game's devs
