Re: Threads testing federation via ActivityPub

Oh, looks like you're trying to fetch user-facing profile URLs like
https://www.threads.net/@christophersu as AS2? That doesn't work. Their
actor URLs are different, eg https://www.threads.net/ap/users/christophersu/
, you can find those in WebFinger responses. And fetching those actor URLs
as AS2 requires authorized fetch, ie you have to include an HTTP Signature
from a fediverse account.

It'd definitely be nice for them to serve AS2 via conneg on user-facing
profile URLs like https://www.threads.net/@christophersu . I'm hoping to
start a conversation with them about interop details like that:
