It's getting harder and harder to assume good intent when we've recently been battered by trolls.
One got suspended for a year, then the three latest got deleted including several incarnations of "poonjay".
I've seen this happen to other sites. You get hit by trolls, then moderation tightens up and legitimate discussions are casualties, people complain, there is the obligatory complaining about how everything changed and the moderators are called various and sundry names, and the site begins to rot.
So.... what do we do?
I say, so long as we just "wonder" about these people, and shut down the questions when they are clearly and identifiably used to troll this site, and keep an eye on the people asking doubtful questions.
I don't think we should be too quick to clamp down on anyone, as the trolls eventually reveal themselves as they escalate quickly when they are not getting the reactions they want.
