I suspect he's talking about the chans or shock sites like you mention. I think even ED had cringey stuff like that on their shock pages (I can't keep up with whatever drama happened there recently). But that's Jake's MO- he actively seeks out the most disgusting stuff he can and then whines about it, even though it's generally only in places you find yourself in by searching for it.But what is this nonsense about dead-and-dissected animal gifs? Who does this? We don't. Even Hitler loved his dogs. He must have fetched up on some rotten.com type site, seen something terrible and come to the conclusion that all bad people are on the same side.
Or he's making shit up.
It's like the busybody Karen that looks up the nearest smut theater in a run-down part of town where no one goes except to jerk off and then tries to start a protest about it... for the children. Except Jake would go in and watch all the movies and tweet about how it's terrible that such places exist to show bouncing boobies (that are almost as big as his) and smooth thin skin of women which is definitely what he is working towards and he'll just have to go back tomorrow for more research even though it's giving him nightmares.
