So long as an obvious dysfunctional pathologic drive manifested by Lastworditis-OCD, attention-whoring fixation to be noticed/responded to, and likely need to overcompensate for a real life inferiority complex (anytime someone tells you that he's smart and you're not says it all), fails to get professionally addressed, you better believe he'll be irresistibly drawn back.
I've understood for a few years that although some of those here whose opinions matter most don't really hold his shenanigans in much regard, they see some utility in keeping him around. Like the wrestling villain universally hated who inevitably ends up losing, they understand that his trolling, aquaism and embarrassing cluelessness definitely stir up emotion and generates forum activity. Unfortunately until now he's become "The Teflon Troll" from years of getting away with twice the self-serving, insulting and sometimes fins-inflammatory BS for which any opposing fan on his own forum would be summarily banned within a week.
As a natural result, he's come to feel enabled and more emboldened in his chicanery. Hopefully when (not if) he returns, for him it will serve as a wake up call that those repercussion-free days of Rainmanish recitations of the same spins, passive aggressive "left handed compliments," never admitting he's wrong, shifting the lines in the discussion sand, and intentional derailment of positive/hopeful/enthusiastic/feel-good fins-centric threads etc, are now in his rear-view mirror.
