The visibility of a user’s “Liked Videos” playlist on YouTube channels is controlled through privacy settings. By default, this playlist is public, meaning any visitor to the channel can view the videos the user has liked. Modifying the channel’s settings allows a user to keep their liked videos private, visible only to themselves.
Maintaining privacy over one’s “Liked Videos” list serves multiple purposes. Users may prefer to keep their viewing habits private, preventing others from forming judgements based on their video preferences. Furthermore, hiding this information protects against potential data mining or targeted advertising based on viewing history. Historically, this level of privacy was less granular, but platform updates have provided users greater control over their data and public profile information.
