Had a couple people asking about this now that Threads is starting to actually federate, so wanted to bump this older post.
We still do not plan to preemptively block Threads, but may in the future if their users and actions don’t comply with our rules. https://shakedown.social/@clifff/110642176464815101
Btw, individuals can block domains too! If you’d like to never see a post from Threads and don’t want them to be able to follow you, navigate over to @mosseri and you can block from there.
Not all apps support this (or will open the Threads app when you click the link) so try from the website if you are having issues
