>>4191242Well there were regular kemono threads in /qa/ back in 2019 and that's around the same time that global rule 3 was changed, so I can kinda see where that guy is coming from but as
>>4191243 said there were a couple threads before the /qa/ kemono move (if you look at desuarchive you'll see one dated as far back as 2017), even if they weren't as regular of a thing as they are now.
So while they probably weren't the direct cause they could've been a contributing factor.
