@emma Well for starters, when I searched my federation blocking UI, my server did not know anything about post.news. It had never seen it before which has.. literally never happened for a federated server since we are pretty well-connected to the network.

Then I checked

https://post.news/.well-known/nodeinfo

and it 404s. Again, not a guarantee but that's a thing most AP servers support.

Then I google searched for "site:post.news [various common words]" and got basically nothing. It's a placeholder site.
