Overview
- The option lets users thumbs‑down posts to train the system to show fewer similar items, with an emphasis on improving the Discover tab.
- Dislikes are not public, posts will not display dislike counts, and the signal is non‑global with limited spillover to a user’s social neighborhood.
- Bluesky says the feedback may lightly influence reply ranking to reduce the visibility of low‑quality replies in threads.
- The company frames the rollout as a test and positions it within ongoing experiments on ranking updates, toxicity detection, and reply controls.
- Power users have criticized Discover for surfacing corny, high‑like posts, and some commentators suggest an effective dislike tool could make the tab far more useful.
