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
No, that’s not how federation works. My instance sends my content directly to everything my instance federates with. No instance takes content from other instances and sends it further - that is not a thing. I sent my content to lemmy.world and it is free to be there. Lemmy.world will not forward that to Threads.
