It might be fair play, however. If I correctly recall, LessWrong had, for a while, a prominent wiki admin who had been punted from Wikipedia for his frothing npov.
I am not aware of Less Wrong having a Wikipedia admin. Are you perhaps thinking about David Gerard, admin of RationalWiki and Wikipedia, who once got in trouble for his decade-long internet crusade against Scott Alexander?
