It'd be one thing if they found his secret tumblr account or something and there was history that people were referencing. But outside of using random (possibly ai generated) anime girls as his avatar, that's the extent of anything I've even seen of him + girl or even him + anime.
The random screaming at him in threads he's trying to talk in gets real fucking old, and it's an old something awful goon trick to harass people, they used it quite effectively against furries back in the day (before one of the furry commission sites compared notes and doxed the SA mods for paying for staggering amounts of furry porn).
And it's not his fault, it's the fault of the people who want everyone else to see what a good person they are for directing the proper 2 minutes of hate towards the designated target of the era. Last decade it was "transphobes," now you get your goodboy points for screaming at Anime fans if you can use twisted tumblr logic to call them a pedo. I'm not kidding when I say they've called college girls with double H cup breasts -- breasts bigger than her head -- "pedo bait." They even caused an international incident with that, pretending to be Japanese citizens outraged that the Red Cross was doing a blood drive, causing them to cancel the most successful blood drive campaign in Japanese history early because they didn't want to piss some bald jew faggot in Seattle who happens to know how to use DeepL.
Hell people have even followed him to his profile page to make damned sure everyone looking on knows just what good people they are for taking a stance against something he never professed a belief in. It's the kinda shit I'd expect to see on Twitter or Reddit, not the farms.
