How exactly would that work? Or, perhaps more specifically, how would the app know whats anime and whats not? muting and blocking the communities yourself would be far easier IMO.

Wrong way of asking it.

“Option to tag anime content” and let people choose if they want to hide it or see every post with that tag.

I’d add more tags (politics, sports, …) but…

You’ve gotta block the communities yourself. I feel your pain, but what you’re requesting isn’t going to happen.

Every time I come across an anime community, I block it. But there are so many that keep popping up…

My block list is filled with so many anime, furry, and shitposting communities. It’s a bit annoying and an uphill battle, but you’ve got to go to their communities and block them individually (but also block the anime instances).

NSFW tags are built into Lemmy and therefore it’s possible to turn that off (whether using Boost, another client, or simply the web front-end). There’s no anime tag, so you’re basically asking for some kind of chatgpt-esque automagic detection of your disfavored content to filter it out.

Much easier to either block what you aren’t interested in from all, or curate what you DO want to see via subscribed, no?

I’m happy with just blocking channels with content I don’t want to see rather than use any nsfw etc type filters. Seems to be tuning things well after a week of blocking.
