I'll put it this way, on the SBA we hold "yearly" surveys, and one of the questions is "what could be done, in your opinion, to improve the league?". Members who have only read DT's inanities in old threads say things like "Well, you got rid of DT, so anything else would be downhill".
We have members who joined who wouldn't join while he was still allowed on the forum, and we have members who have threatened to quit if we ever allow him back.
I hate to say it, but the dude is psychotic, immature, and shows a lot of sociopathic tendencies and should, by and large, be ignored in situations like this(though it IS fun to push his buttons, as he'll fly off the handle at a feathers touch).
When he was banned from our league, before we made it public he made a post about retiring and quitting, and had this giant tantrum full of obscenities directed at individual members who had never been remotely rude to him. Later, when he wanted to come back, he told us that HE forgave our members, and to this day has deluded himself into thinking that his personality wasn't entirely at fault.
Uh. . .Novel. But, TL;DR. DT ain't nothin' but a sack of problems.
