I came here ready to ask the same question for the same reason.
Seems like a really good idea for a future version of lemmy - being able to block almost all porn (on this account at least) by blocking a single instance would be so convenient.
Yep, it would give much more control to the user, also it's a feature already present in mastodon (called block domain over there) so it's not a foreign idea to the fediverse.
Just log in on a normal web browser (not wefwef), search for the community you want to block and enter that page, there should be a block community button there. After blocking they will not show up in your feed anymore (I’ve used it to successfully block all the shitposting communities, so much better)
OP was asking about blocking instances, not communities - e.g. everything that's hosted by lemmy.world, not just nostupidquestions@lemmy.world
As thenother user pointed out, I want to block instances, that os why I pointed out the github threat.
Blocking communities has become really easy though, at least from my app I can block them just by seeing a post.
you can setup your own instance and block federation with instances that way. then use a tool like this to auto-subscribe to all the top communities. https://github.com/Fmstrat/lcs.
I've just done that myself for different reasons but this is a discovered side effect.
Lemmy doesn't have this feature, but Kbin does.
On Kbin, you just go to https://kbin.social/d/lemmy.world (or whatever instance you want to block) and you can block it. You can also follow an instance it if you want to see every single post from every single community on an instance for some reason.

And then you fill up the storage on the poor guy running his 10 user instance on a VPS. :P
Would you? Wouldn't that behave like browsing for local of that instance?
Not quite no, otherwise the load wouldn't be shared. How it works is that when you subscribe to a community (or instance) from that point on any comment, post or interaction is sent to the server you are on, and vice-versa. That way each server serves their users and the servers swap interactions with eachother to allow a certain level of scaling.
Now Lemmy I think doesn't download files (images etc), but points to the original instance, so it's really just the actual posts and comments (which will gradually add up over time). But Kbin, downloads the images and media too. That way, they take the download pressure too.
I've been running for less than a week with around 50 communities. The media storage is up to 5.5GB. Adding whole instances I'm pretty sure would increase the rate it rises quite a bit.
Can you block your users from following instances? This looks like a serious problem if it were not possible to regulate.
I've not looked, possibly you can and make a more curated experience.
Currently just me on my instance (others welcome, but it doesn't appear in fedidb for whatever reason), and I have the capacity to handle the data so far. I'm not that concerned.
Anyone opening to users though should expect to get a lot of incoming data.
Now this is a feature worth changing from Lemmy to Kbin, I was going to wait for kbin to get an update but that is a really good feature.
You could use a userscript extension like Tampermonkey and install this script to be able to block posts and comments from specific instances: https://lemmy.dbzer0.com/post/141704
