What I'm asking is if there are any browser extensions or an app that will just automatically block any community you encounter from a particular instance.
Im kind of tired of seeing all the porn on all and blocking communities 1 by 1 but I don't want to turn off nsfw.
(Also as a side question, is this the community to ask lemmy related questions? I guess it will probably be oversaturated with this kind of post so I ask for future reference, I thought about asklemmy but that is more about open ended questions.)
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.
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.
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.
