You may not like it - but thats how TripAdvisor has always interpreted the policy. Specifically, sexual assaults have always been considered not family friendly. They are removed from the site and referred directly to the hotel for investigation. (disclosure: I worked there from 2010-2013, including a short rotation in the content moderation arm that makes these calls)

My broader point was simply that this isn't a new interpretation of this policy, they've been doing this for years.
