Curators say playlists are being reported for a variety of reasons, though oversight is lacking and claims aren’t properly investigated. Playlists can be reported for a variety of reasons, including sexual, violent, deceptive, or hateful content. As soon as a report is received, the playlist’s metadata is removed immediately. That includes the title, description, and any custom playlist image. No internal review process stops the metadata removal from happening once a single report is received.
