Hi @pfefferle@mastodon.social, I was trying to figure out something else (which I'll ask in a separate topic), and then went down a rabbit-hole when I discovered I could no longer find @notiz.blog (
see, no link!)
NodeBB was unable to retrieve the Group actor because the webfinger response notes its' ID as https://notiz.blog/%40notiz.blog; note the %40. Possibly related, the actor self-reports its own ID as that value as well.
When NodeBB tried to fetch that via AP, WordPress returned HTML
