There is a developer post on this thread:

And it basically says, yes they will be addressing it, but they aren't going to announce what kind of measures they will take because it would defeat the purpose.
I hope they do a better job than other MMOs, at least what I've seen in WoW, there are constantly spammers in capital cities yelling their gold prices.
