Many NSFW have nothing to do with porn. Sometimes are horror contents, some times are crude images, some times are just lazy people who don’t know of the Spoiler tag. Can we have a quick and easy way to filter off all the (very funny but not alway wanted) Porn posts without locking out those other contents???
This system could work if the people who manage anime communities also enforced tagging borderline hentai with the hentai tag, which hopefully most wouldn’t take issue with. You could always still block the community/instance if they don’t follow this system.
Personally I’m not interested in hentai or anime, which is why a general anime filter encompassing both of these themes would be perfect for me.
