Starve them of the oxygen of publicity...

OK what the sam-hill is it with everyone and the goldfarmers all of a sudden?

Getting hit with farmer spam? 

/report and /addignore

If it's getting that bad you could even macro it. Then just target teh bleeders, zap them like the cockroach spawn they are and move along.

I made the mistake of going onto the oForums and brought up 'recent' posts. More than half were people going "!zomgords what to do! there are gold farmers in teh game!" 

Good grief people. grow a pair! Instead of running to the boards with "We need a dev to do something NOWWWW!!!!! I can't afk grind my intrerrtarner* for all the spam" do something about it yourself. Just like any other irritating spamming griefspewing BMs.

Big news, they've always been there. Bigger news, they must see the game as worth farming gold in or they'd not be wasting time there.

Not even going to get into the whole "is it against the EULA / but some people farming credits aren't selling them" thing.  Just treat them like any other annoyance and block them.

*(seriously. How in fork do you write something you see written in front of you daily THAT badly? Sheesh, I could throw an gurnade at peepl who du that)
