list cleaner.
sweep away dead moderation-list subscriptions from your bluesky account. finds every app.bsky.graph.listblock record you've written, then pings app.bsky.graph.getList on each to see if the source still resolves. lists whose creator is deleted, deactivated, or took the list down are flagged — delete individually or in bulk.
sign in to clean up
oauth sign-in via your handle. the redirect will ask for permission to delete your own app.bsky.graph.listblock records — nothing else.
