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 !nokotan@ani.social 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.
But, I never understand. Why would anyone use Lemmy or any social media at work? I am Teen. So, really asking.
