It seems to be working for me. Can you confirm that it's still broken on your end? I know there was a server hiccup on your home instance yesterday causing some odd behavior; maybe that was the culprit?
sh.itjust.works explicitly blocks Threads. They held a vote among the local users: https://sh.itjust.works/post/11308397
It is odd that threads.net appears on our instances page, while the same is not true for other Lemmy instances which have not blocked Threads. Lemmy.world is federated with Threads by default simply because it is not on our instance block list. I do not believe our instance has done anything special to force a link with Threads. I mentioned it in our admin chat and will update this post if I learn anything.
However, even with threads.net listed on our instances page, Threads does not seem to work with Lemmy. I am able to search and view Mastodon user profiles from lemmy.world, but it does not work for any of the Threads test profiles.
Edit: The lemmy.world database has no records for a person on threads.net. Our best guess is that a Threads user tried to interact with lemmy.world. Perhaps the process got far enough for our instance to recognize threads.net and add it to our instances list, but not far enough to create a record of the user in our DB.
Nice! Though I think your "I'm going in" skipped over a link in the chain, and should link to here instead: https://lemmy.world/comment/5482245
Spoiler alert: the drain is just a straight pipe to a bucket below the counter.
The link works for me, though the image is slow to load. I restored the post so this can be part of the chain.
As for the downvote, I assume it's related to some Lemmy users simply not liking to see Reddit culture here. Haters gonna hate. Have fun and don't worry about it.
It's in the "Blocked Instances" section, where it should be.
