Well, the only issue I see here is that the 'difference' between general and local trolls is while trolls in local you can just walk away from, trolls in general span the entire map. Once they say something, there's no taking it back. Everyone in the map has seen it. Unless you feel like leaving the map, there's not many other options to 'instantly' stop them. But like said above, that's fixable via the handy dandy block button or reporting.
There's always going to be trolls, yes. That's a given. Some of those trolls have matured, and others not so much, and there's always new ones. But like you said, Hakumi, the news spreading that General chat is back? That'd boost activity. Now this might bring back some not-so-friendly faces, but at the same time, I think the amount of people on here would be taken up a notch. I'd really love to see General brought back; a lot of people would, though I guess this bit is a tad obvious. Maybe even bring it back for a 'trial run' for a week or so? Then depending on how it was used/misused, the final decision would be released with the next update.
Hearing that the game both updated, and general is back? Here come more names to the game, woot!
Just thinkin' aloud. Would be neat to see that green chat put back into play.
