I read this post and have been pondering this question for a good chunk of the day. I had a thought that may or may not have any impact. I hope I can convey this correctly.

Say Lemme.ee defederates fromThreads. But we are federated to Lemmy.world. Because we are federated with them, and they are federated with Threads, is there going to be some…Threads posts leaking though to our all. Or does the all feed only extend one…“hop”?

My brain keeps going to something akin to six degrees of Kevin Bacon. I know it’s not the same, but wasn’t sure how the fediverse handles the “all feed”. One hop… two hop…etc.

Thanks for any insights from people who actually know how this works.
