Am I missing something? The community you linked only has one post.
I've noticed the user you've mentioned reposting some of my greentext posts to similar communities on different instances (and vis versa), but that seems harmless. Maybe even a needed service.
I've seen plenty of complaints about lemmy.ml being the worst offender for this, removing stuff that is so innocuous that you could show your grandmother at church, because someone in charge found a contorted way to be offended by it. (or worse, because it was critical of China or something)
I think users will ultimately find the path of least resistance, and the least heavy-handed instances will have a healthier growth.
Thanks for keeping the lights on. The effort and time is appreciated.
