The biggest surprise for me was the https://hexbear.net count, an instance I hardly interact with.

Community Count:
Community Users:
They can be oriented to some type of content: For example, the many feddit.something are targetting people by countries or langages (.it, .uk, etc.). slrpnk.net is solarpunk oriented, mander.xyz science oriented. Litterature.cafe is books, reading and writing oriented.
And they can offer different moderation policies: People on lemmynsfw.com probably want to see NSFW content. lemmy.world has a policy against it. lemmy.dbzer0.com allow for open discussion about piracy that many instances forbid and so on.
It you don't see the difference in instances, it is probably that you are about fine on your local instance. But if one day, you hear about a community you can't access, maybe that is because it is blocked by lemmy.word and you could access it from another instance
If the dbzer0 instance allows piracy talk but I'm signed up to an instance that doesn't allow it, can I talk in their community or do I risk being banned from mine?
In other words, are my comments stored on their instance or on mine?
Lemmy stores your posts and replies on both your host server and on the server of the community.
One interesting behavior to note here that is different from reddit is that while comments on reddit belong to the profile of the person commenting and is then imported to view in the subreddit (this is why you can edit comments after being banned, and why there visible in your profile even if removed from a subreddit), on lemmy the target community is instead authoritative and your host server will by default respect a deletion by community mods on different servers by also removing that comment from your profile.
Very interesting indeed. Thank you for letting us know.
Your comments are stored on both. The "canonical" version would be on your home instance but every instance that is federated with your instance would get a copy of your comments. I think it's even possible to have your content removed from one instance but not another. One of my posts shows as removed in the mod log but isn't actually removed.
So by default your instance respect mod removals.
You can change that as a server admin, so comments would remain visible to other users on your instance.
I think your instance is authoritative for content of comments, but the community hosting instance is authoritative for which comments are approved (other instances respect such removals by default)
That's a good way of putting it. While my instance holds my canonical comments and the communiy's instance holds the canonical list of comments on a post, if the community's instance isn't federated with my instance (or the pair temporarily cannot communicate) then my comments won't show in the list.
That's weird. @Natanael@slrpnk.net says the opposite is it a question of version?
Test comment. Verifying something. Will reply in a separate one instead of editing this.
If you want to run some more test, here a community dedidacted to that: !testfediverse@jlai.lu.
You can be as thorough as you want without worrying about spamming people (^_^)
Alright. I wanted to verify something to double check. Here is the flow of how my comment gets to your instance and is visible by you. It helps when you realize that all communications you do are with your instance. I might get inbox/outbox terminology reversed or wrong.
I say the canonical copy is on my home instance because imagine a scenario where lemmy.world is NOT federated with programming.dev but for whatever reason programming.dev didn't defederate back. I could still see and comment on !fediverse@lemmy.world. Other users of programming.dev could see my comments and reply, but nobody else.
This is how I understand federation to work but it might be incorrect. It's a complicated topic. It might be that your instance directly gets the comment from mine.
I need to take time to read you comment quieltly. Honestly, I start to be confortable about how federation work from a user perspective but I have no technical knowledge about it.
You can talk on their instance. If the moderator of your instance dis not wanted you to interact with this other instance they would have block it.
That I'm not sure. But I think there is a copy of the content you accessed on your instance. Maybe someone administrating an instance could answer you better than I did.
I signed up at feddit.nl and I am not even from Netherlands.
Which feels a bit as a sleepy instance, but maybe I'm not in the right communities.
If you find yourself well were you are, then you are in the right place (^_^)
So which instance an account is from matters regarding which communities you can join? Huh.
Only insofar as some instances block communication from some other instances. Not mine though, that's actually one of the reasons I picked it. That and it being by an org that's older than the web and runs a public unix server and a bunch of retrocomputing type services as well as fediverse stuff. They started out as a dialup anime BBS.
Yes but not so much. The fediverse is a big place and everyone can open a community in the same topic in a instance that is not block. Look how many zero waste there is !zerowaste@lemmy.ml !zerowaste@slrpnk.net !zerowaste@lemm.ee !zerowaste@lemmy.world !zero_dechet@jlai.lu. And they may be more on instances I don't know.
For what I have witness instances blocked each other over divergence on political activism. If you don't plan to go discuss with people who really want to convince you to become communiste, you should be fine.
Go on [your.instance]/instances for the list of block instances.
