Haha welcome, wait until you get to the politics. Anime, maybe you can block, left extremists, no way, not a chance.

But you are overthinking it, searching by all basically got removed from reddit, because only like every 5th post wasn’t nsfw. And now you joined the less moderated reddit, ofc you are seeing more trash. Just block it, and move on. Or browse by subscribed, I do, and I see none of that.

The anime community isn’t stereotypically known for having a loving marriage. And I have an idea of what pictures you are talking about. Pretty bottom of the barrel stuff. But hand drawn art is important. Especially these days, even if they’re wierd. So, if you don’t like it, please just ignore it. This isn’t worth getting worked up about imo.
