The committer's email is saved in commits and, for the public repositories, the email is revealed to anyone on the Internet. To increase users' privacy, implement a substitution of the original email by a personalized no-reply email, e.g., bob@users.noreply.bitbucket.org. This way, the commits can be still associated with their author, but the user's email will not be revealed.
