@vkc @mkj @draeand ClearSky https://clearsky.app collects the blocked accounts on from AT Protocol (Bluesky) data feeds, and it will show that data for publicly visible accounts.
Data is only hidden for those accounts that have been set to be visible for only the logged-in Bluesky users (even though the data itself is still publicly accessible via other AT Protocol tools, even from those "hidden" accounts).
