There was apperently a karma issue that derailed the thread later, and a significant portion of the thread ended up nuked. I've norated the party at the root of that derailment.
Some times when a thread is headed off into tangential and volitile oblivion, you have to moderate it somewhat. Nukeing isn't necessarily permanent. I suppose in this case I personally would have locked rather than nuked, but its a judgement call at the time of the occurance, and one that is the call of the admin making the decision.
