These are from a user deleted back in 2023, I was able to recover the data from pixiv's servers. You can recover most images of users deleted in the last 2 years, since the files are still on the i.pximg server, just no way to find them. Older deleted files I had a low success rate with. You can read about the technique here: https://www.reddit.com/r/Pixiv/comments/1iyltgq/comment/mgaktxw/

The ai art is bad but some of the captions are very good, generally they are about loss of human rights, findom or ejaculation control. Skip about half-way in to find some of the better captions.
