Why YSK: Choosing an instance with defederation policies you’re most comfortable with is important to make your Fediverse experience smooth in the long run.
Here is a chart showing the defederation count of each instance.
| Instance | Defederated with how many other instances |
|---|---|
| beehaw.org | 405 |
| feddit.de | 101 |
| lemmy.world | 63 |
| lemmy.ml | 44 |
| sh.itjust.works | 4 |
| exploding-heads.com | 3 |
You can get it by going to the instance’s instance list and scrolling/Ctrl+Fing down to “Blocked Instances”. To find the instance list, go to https://your-instance.url/instances, for example, https://lemmy.world/instances
Lemmy.world users can see behaw posts, but beehaw users can’t see Lemmy.world posts. Comments cannot be seen by anyone outside their home instance.
Beehaw defederated from Lemmy.world, but Lemmy.world did not defederate from beehaw.
If you look at a Lemmy.world community through beehaw, you will only see posts from before defederation, or posts made by unaware beehaw users.
What do you mean by comments cannot be seen by other instances?
If instance.c has defederated with instance.a and instance.b, instance.a can still comment and post on communities from instance.c—but neither instance.c nor instance.b can see those posts and comments.
