It's unclear to me how much it's porn to pervert to troon, and how much it's autism to troon to porn pervert troon. Especially since autism is presumably over-represented in discord moderators.

There are definitely a lot of autistic men/boys who get convinced their social weirdness is actually because they're a cute girl inside and if they just take these drugs they'll become a socially normal kawaii girl just like in their anime. Then once they're in, the "support groups" are essentially industrialized grooming, and they end up crazy perverts. Some of the screenshots I saw a while back from one of the kiwifarms vs. crazy tranny episodes was pretty eye-opening. These people are able to operate in the open and in huge numbers to push some really extreme degeneracy- in this case it was how to make bathtub hormones, or "girl juice" as they call it- and banning that shit, and everyone who participated in it, would definitely be a great first step, possibly more effective, and definitely easier, than banning porn.
