A couple weeks back there was an announcement at the SWG site that they were looking for volunteers to be part of their new Warden program. They were looking for about 30 responsible people for each server who would be given the ability to silence anyone spamming credit sales or power-leveling services.
It went into effect a couple days ago and Mos Eisley is once again a happy place to visit. The first couple days you still saw the spammers sitting there, but the Wardens were doing their job and no chat was coming across the chat box or in chat bubbles over their heads. Today they just weren't there at all.
I've seen complaints about greedy SOE being too cheap to hire people to do this, blah blah blah. I think it's a great idea. A lot of players love helping to making their server a better place to be. And I think it's great for a company to have enough confidence in players to make them part of the process.
