The Source: The Dick Show Episode 313 2022, June 19th, Dick on Internet Father's Day , Timestamp 2h1m31s to 2h1m52s, I posted this clip in your MATI thread and I guess it made its rounds to you seeing it here, it was also unrelatedly referred to in the Dax thread in Internet Famous where they were trying to get your attention about it.
420chan's owner ran a very questionable board about kids, and the owner of that chan was also the one that claimed they hacked gofundme and published the list of donors of the truckers, but that latter act seems questionable. They seem like a lunatic, and Dick interviewed Internet Hate Machine about that person. On a side note, she decided to create her own chan in the style of the oldschool ones, with lots of freedom, sans furries and kid lovers.
