Meta just announced that they are trying to integrate Threads with ActivityPub (Mastodon, Lemmy, etc.). We need to defederate them if we want to avoid them pushing their crap into fediverse.
If you’re a server admin, please defederate Meta’s domain “threads.net”
If you don’t run your own server, please ask your server admin to defederate “threads.net”.
And whenever an account from Threads upvote/ downvote or reply to your comments/posts or vice versa, Meta will analyze that and they can sell ads based on your political leanings, gender, geo-location, hobbies, marital status etc.
That’s the options from what I saw from fb ads dashboard years ago. If you’re from US, that options are broader and more detailed.
