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

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?

[–] JackbyDev@programming.dev 3 points 3 months ago (8 children)

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.

[–] pseudo@jlai.lu 1 points 3 months ago (3 children)

That's weird. @Natanael@slrpnk.net says the opposite is it a question of version?

[–] JackbyDev@programming.dev 2 points 3 months ago (1 children)

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.

  1. I post a comment to !fediverse@lemmy.world, but it is done through https://programming.dev/c/fediverse@lemmy.world. this goes to programming.dev's inbox.
  2. Because lemmy.world is federated with programming.dev, they scoop up my comment from programming.dev's outbox
  3. Because jlau.lu is federated with lemmy.world, they get my comment from lemmy.world.
  4. When you view !fediverse@lemmy.world through jlau.lu/c/fediverse@lemmy.world you will see my comment from your server's copy of it.

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.

[–] pseudo@jlai.lu 1 points 3 months ago

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.

[–] JackbyDev@programming.dev 2 points 3 months ago (1 children)

Test comment. Verifying something. Will reply in a separate one instead of editing this.

[–] pseudo@jlai.lu 2 points 3 months ago

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 (^_^)
