I've blocked 40ish instances and hundreds of communities. Everything I find boring, not interesting or trying too hard.

29 communities, mostly news. I'm here for memes, not links to articles.

Also a few atheism communities, because I'm not a fan of seeing posts bashing my religion from a community where the rules forbid me from saying anything in its defense.

Around 40 communities of irrelevant or annoying stuff.

Only those with other languages that I do not understand and that somehow still show on my feed.

About 330. A crap ton of porn stuff, furry, bondage, etc. Several non-English communities. Operating system related stuff like Linux or android. A few “normal” communities that are on instances that don’t allow much dissent or contrary opinion.

Almost 200 pretty much exclusively from lemmynsfw before you could block a whole instance.

Once they added that, I've blocked very very few communities.

1500+

over 30. I personally prefer more serious discussion because I'm a dork. I'm not into most sports, jokes, video games or other whimsical stuff. I like some of that stuff IRL, but I consider the internet primarily of use for deeper discussion of topics that most people might not necessarily have an interest in. Like NASAs nuclear powered project Orion spacecraft in the 1960s.

Peoples eyes normally glaze over when I talk about that stuff offline, but there are billions online, and usually someone else finds that niche stuff as interesting as me.

It would be nice if you could select which topics interest you rather than having to block every community that does not.

I mostly use All as well. I have the following blocked:

• all the meme communities that pop up. It's just spammy posts

• all beehaw communities. Mostly because they were defederated with the largest lemmy communities, and I didn't want to talk to only a small subset of users. Not sure if they've changed anything since

• hexbear because... Hexbear

I try to block communities discussing politics, cringe memes and Linux. I have about 50 blocked at the moment.

Zero.

I have my main feed as no NSFW. I might have half a dozen blocked.

My NSFW feed, probably has 40+ blocked.

I've blocked 10 or so instances and over 500 individual communities. Mostly by browsing /new and just killing anything I don't have the slightest interest in.

The instances I've blocked are leftist, furry, porn and anime related, plus one that's hosting sports communities exclusively.

None, the insanity I sometimes encounter can be entertaining. I'll just log off if its too much.

I don't know, but it's mostly memes and gay stuff.
