Yeah, he organised "the largest case of mortgage fraud ever in Illinois" and made off with $600. It's amazing you are still breathing. How do you think he pays for a studio in Manhattan, streaming internet TV, and international filming jaunts to Tokyo?The man hasn't had a job in the last decade.
To me it seems more like what happens in the furry fandom, where when one of them gets caught on camera in the news doing something embarrassing or illegal, the rest of them immediately freak out, turn against them, and try to distance the community as far from that person as possible by any means necessary. It's a rather sad source of drama in that fandom, and, sadly, is a major source of entertainment for SA goons and anyone else who likes to pick on insecure nerds. Really though, as you said, they just shouldn't care.
Yeah, people should just not care when other people get caught fucking animals

. Nobody cares what you get up to when you are wearing your yiffsuit but the moment you lay a hand on a real animal or child, damn straight you should be villified. As for Bruce, the Bitcoin community should have washed their hands of him the moment he was outed as a fraudster. No drama needed... But too many people were too proud/stubborn to admit they had been wrong about it, so it turned into a protracted battle.
A pseudonymous marketplace like Bitcoin relies on scammers being ostracised. If you value bitcoin and want it to succeed, you should write Bruce off ASAP
