The account was suspended. Reason for it is a bit unclear, at least to me. Title message was " Regarding realistic images that could be mistaken for real-life photographs " but description how they do not allow other people's content (model). And that one of the guidelines were broken, so I guess two mentioned?
They didn't say which work was a problem either. Pretty sure everything was censored so that shouldn't be the case.
I was done with SourceFilmmaker before pixiv suspension anyway. Maybe I post Blender content one day but no idea when since I also need to learn how to use it etc.
