You answered your own question;
He abused the trust system and got kicked off DT for that -- an abuser.
I'm not even sure how to interpret this incoherent post, but I would say that even if the forum were better off without TECSHARE, I still mourn his passing. I mean come on, he'd been a member of bitcointalk for a long time and did a lot of trading here, and he was certainly respected by a lot of members. So fuck you and your pissing on his grave.
y -> ing.
A typo did change the overall meaning.
I don't think we should celebrate assholes after they leave a community; especially if the individual has personally attacked you. He made plenty of claims about me in the past in the threads in Politics and Society; including dozens of moderator removed posts due to repetitive ad hominem insults.
