If you want to block a possible future Meta instance from your instance, here is the domain to block:

threads.net

(and you might as well block instagram.com and meta.com and facebook.com too, in case they use subdomains from them)

It may be advantageous to also preemptively block threads.instagram.com, which I believe they may use as a secondary. Even if they don't, it seems like a modicum of effort for safety's purposes when you're already right there.

If you block instagram.com that will automatically block all subdomains too. Same goes for meta.com, facebook.com etc.
