Answer: Kero the wolf is/was a popular furry fandom Youtuber who in 2018 ended up being outed as a zoophilia/zoosadism fetishist due to a leak of private data that led to evidence of underground zoophilia/zoosadism networks involving a number of furries. Kero's name was one of the name's mentioned in the leak. When offered the chance to answer the allegations he instead lied about it. Then doubled down on his lies despite being confronted with video evidence of him abusing his own dog. You can read more about all this here.

So, yeah-he's a sick individual who's into some pretty nasty shit. That said i'd avoid that sub like the plague. Nothing good goes on in there.
