The linked boards don't have content on them.
You can report posts with the report form at the bottom of the page.
I dunno if reporting boards is necessary. They can open a new board, look at how many they dedicated to what you claim to be monkey torture. Not sure how can sou tell. I mean "monkeyhate" could be a giveaway, but it could be hating on any kind of people essentially (like how Brazilians are called monkeys on imageboards).
As for telegram link, or links to stuff in board description, we're gonna discuss it.
Btw, if you see monkey torture, pls report. "Animal crush" is not free speech.
