Except that’s not what happened. Hal was warned, several times and ignored the warnings. His ban wasn’t just justified, he worked hard to earn it.
Any other version, including calling any of his posts in the last year, at least, “useful” or “helpful” is gaslighting.
I can tell you that nobody is banned for expressing opinions, even negative ones, nor is it ever done lightly. Suggesting otherwise is, frankly, offensive.
