  Recommender systems are becoming increasingly central as mediators of
information with the potential to profoundly influence societal opinion. While
approaches are being developed to ensure these systems are designed in a
responsible way, adolescents in particular, represent a potentially vulnerable
user group requiring explicit consideration. This is especially important given
the nature of their access and use of recommender systems but also their role
as providers of content. This paper proposes core principles for the ethical
design of recommender systems and evaluates whether current approaches to
ensuring adherence to these principles are sufficiently inclusive of the
particular needs and potential vulnerabilities of adolescent users.
