As a new reddit exile, I may be misunderstanding this.
In theory something like a !gaming community could crop up on multiple large instances, especially during the mass exodus while instances are getting hammered with spikes in volume.
If that’s the case, we’ll have fragmented communities across instances. Is there any way besides subscribing to each of them to combine them into a sort of multi-reddit type aggregation? Or is this considered a temporary (albeit important to adoption) problem during the crazy stages?
I’m as new as the next guy, but that certainly doesn’t mesh with my understanding of federation at all. Per my understanding, communities are completely unrelated across instances. AITA on lemmy.world can be run by UserA and have SetofrulesA with BanlistA, while AITA on lemmy.ml can be run by UserB with SoR-B and BL-B. AFAIK It’s the entire point of federation, that if I don’t like how AITA on lemmy.whatevs is run I can spin up my own and go on my merry way.
Perhaps someone more in the know will turn up but I believe that you were told wrong.
