Check the modlog for proof, a discussion post about moving this instance to an instance that shan’t be named now got removed for “linking to instance featuring pedo content”.
Ironically that exact possibility was reason for the discussion in the first place so seeing it happen this quickly is a bit funny.
Not sure how best to go about linking to said instance since it seems to get your content removed. DM’s would be the only solution I guess but not sure if those are checked as well.
Maybe link to a community which can then link to the actual target? Both beehaw and lemmy.world have general anime communities. Not a perfect solution, granted, but it might be a usable workaround.
