Okay I just got lucky.
Pretty sure the creators username is Nozodora, he has a pixiv with the same "UMATok" overlay, it looks like his works are distributed through discord now so nothing on kemono, but he at least used to make videos.
This guy on iwara uploads compilation videos, some of the other "UMATok" videos credit to Nozodora, but unfortunately the Teio one is private so I can't read the description.
