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

The data this is based on comes from https://lemmyverse.net where you can just download a full json of the data they have (I excluded all communities marked as "suspicious")

Community Count:
Community Users:
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?
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.
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 (^_^)
