In reviewing the Fedipact page, I noticed the message about Threads having moved to threads.com nearly a year ago. In reviewing federation status with the Federation Checker tool, I noticed that most Lemmy instances don’t appear to have added threads.com to their defederation lists. Is Threads able to federate with other Fediverse instances using its new domain?
That depends on whether the software allows it; Mastodon uses the AUTHORIZED_FETCH variable for this. If it’s active, blocked instances can no longer fetch posts via AP.
