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
if your instance defeds threads then it blocks any information being sent to threads at all so they wont receive anything that you post, not even your upvotes on posts will federate with threads.
The only case where this gets kind of weird is if you’re on an instance that federates via an allow list of approved instances instead of using the normal method of federating with everyone by default then blocking selected bad instances (the only large instance that uses this method for federation though is hexbear as far as im aware so its not really that important).
Thank you for your explanations!
