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
Fedipact is people who’ve signed some thing pledging to never federate with threads, whereas all the other ones have just defederated them without signing the pact. In reality there’s not really any difference at all.
