@silverpill@mitra.social I think given the addressing limitations of collections, this by-proxy method of determining who to send an as:Follow to makes sense as a stopgap measure until ActivityPub's next version...
@liaizon@social.wake.st @scott@loves.tech likely a bug with Hubzilla as it's working when tested against NodeBB (and I think Mastodon)
Can you send me the JSON payload for an Update activity?
