For anyone wondering if Threads and Facebook at large will be a fine neighbor in the space and compatible with other apps/services in the fediverse: they’re already automatically hiding comments that mention Pixelfed https://mastodon.social/@dansup/112126250737482807
A quick search leads me to https://fedi.tips/ which has a lot of information. It mostly focuses on Mastodon but it generally applies to Lemmy and any other Fediverse app as well.
You probably won’t find any source specifically saying that “content is not forwarded from remote servers to other remote servers” because that’s just not how it works. The documentation will probably focus on what it actually does rather than all of the infinite things that it doesn’t do.
Awesome, thank you!
