Chiming here since I am reading though comail docs regarding re: reputation portability and also interested as a future PDS operator. I am also thinking how moderation/labeler services will adopt these through the current reporting APIs plus Bluesky Chat (or chat alternatives like Germ Network [if programmatic access will be implemented in the future, might ask @tessa.germnetwork.com for thoughts] or Matrix) for PDS admin notifications in case their email is not public for privacy reasons.
Also CC’ing @scottlanoue.com in the thread by the way.
