  In this position paper we draw attention to safety risks against youth and
young adults that originate through the combination of online and in-person
interaction, and opportunities for AI to address these risks. Our context of
study is social matching systems (e.g., Tinder, Bumble), which are used by
young adults for online-to-offline interaction with strangers, and which are
correlated with sexual violence both online and in-person. The paper presents
early insights from an ongoing participatory AI design study in which young
women build directly explainable models for detecting risk associated with
discovered social opportunities, and articulate what AI should do once risk has
been detected. We seek to advocate for participatory AI design as a way to
directly incorporate youth and young adults into the design of a safer
Internet. We also draw attention to challenges with the method.
