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.
Well at first I assumed there was probably validity to what Dessalines said, because I consider them credible and I know enough about anime to know that there is a lot of csam that hides behind bullshit justifications. Even in this thread there's discussion of a show that blatantly tittilates the audience with underage characters that would absolutely qualify as csam in any other community except in the anime community, for some reason.
And then I went onto the anime lemmy everyone is surreptitiously talking about, and the literal first post I saw was a body pillow design featuring an underage character that is right on the line of being csam. It was the only example I saw in my brief look, and it didn't quite qualify, which is why I came back and deleted my comment.
I don't care about what the maintainers' view of the matter is, I make (and sometimes delete) my comments based on my own view of it.
If anime is child porn, then so is all live action media.
Not all anime of course, but you've got to be delusional to believe that the depths that anime sometimes sinks with regards to loli and shota content is matched by other mass-market mediums.
I may have an extremely warped opinion on this due to several reasons (imo mostly due to irl encounters with adult people that would put you on a watch list due to how young they look) but I think in the end it usually boils down to anime/manga just being terrible media for portraying how old a character actually is. The oldest anime character you can draw will still look significantly younger than a person you meet irl simply because the art style hides a lot of the age marks.
Edit: which is not to say that there isn't a lot of CSAM hiding, it's just imo the stuff that gets popular on SFW platforms is rarely that stuff
