"someone who views child porn is also more likely to view bestiality, this is a reason why we should shutdown encryption" Paraphrasing.

That conspiratorial guy is... Ugh. At times, his arguments don't even make sense. What does that have to do with that? Hm?

Also, it's likely that if someone is committing a more serious crime, then maybe committing a less serious one (if it is a crime) isn't that much of a big deal to them, or that a space which doesn't moderate that is also unlikely to moderate the lesser thing (or it might have gotten through the same way for a bit).

It's not a conspiracy, and it doesn't have to mean anything meaningful. Maybe, it's even a coincidence. And either way, I don't see how it's relevant.
