Someone (later called a hacker) said Threads was still on the Linked Instances column, not the Blocked Instances column.

To be clear, I did not call that person that said that a hacker.

What I said is that when the hacker screwed with our settings due to the XSS vulnerability, they added threads to the allow list instead of the blocklist

I have this but I don’t see Threads on there.

Please edit that link out of your post. The tool you have linked to is developed by kiwifarms, and it has no place here.

You can find our list of connected and blocked instances via the “Instances” link at the bottom of every page.

https://lemmy.blahaj.zone/instances

threads.net is on that list

If Threads is defederated, does that mean Meta/Facebook are as well?

No, because threads is the only meta application that is going to federate with the fediverse. If other meta services announce plans to connect to the fediverse whilst hosting hate groups, we will defederate from them too
