Maybe DU's dinosaurian forum SW lacks the function, but most forum SWs I've used (and been a Mod in some) allow Mods to move threads to more appropriate forums, if appropriate. I've done it scores of times. So unless DU's dinosaurian forum SW lacks that basic moderation function, locking the topic was a political act, not forum Moderation.
I've not noticed brooklynite being an "obnoxious, pretentious, insufferable ass", but I haven't studied DU-folk that much. But I have noticed in threads here that he is far more realistic than the average DUmmie and frequently pees on DUpipo's Snoopy-dances. IOW, brooklynite has probably for 2 decades walked the border between posting useful accurate information and being a constant irritation (by being accurate).
Is FFR always a permanent limbo status? Or do FFRed members ever emerge to post again?
As others have pointed out, he's a limousine liberal who is constantly talking about how rich he is and how much money he donates to politicians. I find the manner in which he presents himself in this manner "obnoxious and pretentious". As far as "insufferable", his constant name-dropping and "look at me" posts passed the point of annoying a long time ago. Particularly, because the source of all his supposed wealth is his wife. He is a transportation planner for NYC, which isn't a particularly lucrative, nor interesting, job. So outside of talking about how he spends his wife's money, his conversation topics are reduced to talking about water leakage in subway tunnels. As far as being an "ass", he's a DUmmy so that's self-explanatory.
Some FFR'ed members have been allowed back in but I don't know about this one. It's doesn't appear he got banned due to hides, which means EarlG would have had to manually FFR him. But he may beg his way back on with the provision of a sufficient "donation". He would, of course, be required to quit introducing facts into their echo-chamber.
