I believe a few of his work are commissions and such. If you check his fanbox, many of the ones sourced here are the same as those meant to be for his pledges (so more like, he uploads and the after a while set them back to his account/fanbox)
I haven’t seen him upload too many on his pixiv with twitter being mostly where he post however the problem is that twitter being the cesspool of shit that it is I’m not surprise he might have gotten his work flagged or something, whether by people who see his work and get offended because of it recently being Vtuber nsfw art (this happens more often than you think) or from people taking his art and reposting inappropriately thus getting those posts flagged and trancing back to him. Yeah, it kinda sucks. Or it might be something else.
He is the only other well known artist that have been exclusively doing nsfw vtuber art (not all of them are but they do stay within questionable.) I just hope he won’t become a ban artist or anything with all the deletes because he’s one of my favorites.
