Hi. I am a user of soyjak.party and would like to try to explain the baby monkey torture soyjaks because people here have been confused by it. The site is a frequent victim of both bot and manual spam, with gore/shock content (like baby monkey torture) and CP being commonly spammed, for example. The baby monkey torture spam on the site is how they came to be created in the first place, as a way of getting some kind of humor out of the spam on the part of the creators of the baby monkey torture soyjaks, I'd assume. The site has no hidden baby monkey torture community or anything. It's just an imageboard dedicated to shitposting.
Also, vidlii was bought out a while ago by an individual known as Kuz, mainly known for his obsession with attempting to purchase altchans from their owners (including soyjak.party, hence his relevance to the site) who is unlikely to do anything about the baby monkey content being posted on there due to the history of the kind of stuff he tolerates being posted on his sites. He has an article on the soyjak.party wiki that has a lot of info about him (of course some of it is shitposting due to the nature of soyjak.party. It's still a starting point, regardless.)
