So I've been wondering, how do I see if I'm seing a post from a server that's defederated from the instance I'm registered on? Like for example beehaw, which defederated from lemmy.world.
If you are looking for the reverse of this, there is a tool that shows that information, but the creators of it are suspicious to say the least (as in, will openly associate with KF kinda suspicious)
Well that’s true with every platform. Even on Reddit, you could get instabanned from like 50 subreddits run by the same powermod for saying a no-no word; that too automatically via a bot.
The map in particular is extraordinarily cool but rather difficult to discern useful info from. I can tell you from it that lemmy.world is currently defederated by only one other Instance. Which is easy to figure out from there at this point.
I deal with it by going to the remote instance and checking there, as outlined already. All the Lemmy instances I sign into only block for spam, very sparingly for content. So I don't have to worry about local blocks. The one I always have to check remotely is beehaw.org because they house many communities of interest for me and block outside instances liberally.
For any given instance who decides what other instances to federate with? Is it just the arbitrary decision of the server maintainer? The mods? Democracy of the users?
