One more feature people loved about ClearSky is now on Skylens. You could already see which blocklists you're on. Now you can also see who subscribed to those lists. Everyone who subscribes to a list blocks all of its members, often without even knowing who is or will be on it. skylens.redflag.ps

Skylens needs no login and sets no cookies. Your search stays in the part of the address after the # and never reaches the server. Only labelers that block requests from a browser are queried through the server, without logging.

Ten more labels sit on individual posts. A click on a category jumps to the posts in question and shows the start of each post. XBlock, for example, flags three of his posts as possible Twitter screenshots.

The verification tab shows who issued the blue check. For JD Vance it was Bluesky itself, in June 2025. The identity tab shows the history of handle and server from the PLC directory, so renames and moves between servers become visible.

“Blocked by” lists every account that blocks him, newest first, with the date of the block. “On lists” shows every list he has been added to, curated or moderation list, and how many people subscribe to each moderation list as a block.

Labels come from labelers, and each labeler keeps its own. Skylens asks every reachable labeler, around 240 of them. JD Vance’s account carries 16 labels, among them Racism and Transphobia from Northsky Moderation and MAGA from Skywatch.
