There was a video he put out about how there's no way to fight accusations he's an addict, then goes off on a huge list of reasons why.
It was conspicuous to me that he did not mention going sober for a while to prove he could. In private, I speculated it was him being afraid mentioning it would get people on board with the idea, and get simply didn't want to invite the problem.
I think that this rant raised the same thoughts in his audience, and they challenged him in to do it in discord or something.
