ani.social seems like it may specialise in anime stuff. I blocked several of their communities in grounds of not labelling nsfw. That’s about as much as I know.

The problem is definition of NSFW is different for all Lemmy user. One time I posted a Official Art of [email protected] and it got reported for not labelling NSFW. That pic doesn’t even have any thing like Fanservice or Showing Clothes. Just normal School Uniform.
