In reviewing the Fedipact page, I noticed the message about Threads having moved to threads.com nearly a year ago. In reviewing the federation status of various Lemmy instances with the Federation Checker tool, I noticed that threads.com doesn’t appear to have been added to their defederation lists. Is Threads able to federate with other Fediverse instances using its new domain, including those that have defederated from threads.net?


Isn’t blocking one way? So you can block threads but threads will still receive your content?
By block I meant defederate, as described in my post, rather than a user-level block. Just clarified the title; apologies for the confusion.
Defederation ensures that content isn’t received from or transferred to Threads.
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.
