I wasn't here when that forum area was open, but David's right, whatever issues they were having don't go away just because certain people may not be around the forum anymore. Others will certain take their place!
I'm an active member in a health-related forum that has many off-topic threads. It's basically not moderated, with the creator (company rep) of the forum stepping in only occasionally. Things get pretty heated sometimes but usually settle down after a time, usually after someone(s) been pounced on by several of the other outspoken members!l I've been there long enough to see the even when a "troublemaker" leaves in a huff, someone else always comes along doing the same things. Personally, I'd like to see it moderated just a tad, but that's the way they have it, so...
Not saying I wouldn't like to see it reopened here, but I can certainly understand why they would prefer to keep it closed.
Just my two cents...
