Before you comment, please know that I’m not complaining. Someone asked this in Mastodon and it’s a good question because if you don’t block Threads dot net, then you can look people up and follow them and vice versa.
In my home feed I see posts from other Mastodon servers but not from Threads. Why is that? Thanks in advance
Edit There are no Threads dot net posts in my Global feed either. And I haven’t blocked Threads either.
I’ve never blocked threads, but i can’t even follow my own threads account (which i setup explicity to test the alleged feature).
Honestly I don’t think they are actually federated, maybe at one point they had been but it broke and they just didn’t bother fixing it because they already got all the positive PR they’re going to get from it at this point (and really it was mostly negative)
I run my own pleroma instance, so it could be that pleroma doesn’t support it and mastodon does, but i’ve really not seen any evidence of threads being federated with any mastodon servers either. If they do exist I’d love to see any example of a threads user organically interacting with a non-threads users, but i dont think it happens.
Edit: Did some testing using vivaldi.social which is for sure federated. Threads basically blocks all interactions to Fedi, they just make their posts visable to activitypub but NOT the other direction so any interaction is essentially one way. Threads users can see if someone “liked” their post on fedi, but they can’t see replies, or mentions, or post mentions of other non-threads usernames.
Really makes me think the whole “Fedipact” blocking things might be over blown, Meta is actually way more afraid of fediverse then we should be of them, after all, they can’t run ads or harvest data on other federated sites they don’t control.
