User-Generated Content question

Hey,

I have an application for professionals in the medical field and their patients, and I have a question about AppStore Guideline - 1.2 User-Generated Content.

In the application there is a one-to-one connection between a professional and a patient. I want to add comments and chat features but I don't know if I need to do something regarding to 1.2.

I don't expect to have any abusive content from any user due to professional service so the question is do I need to implement all those mechanizm to filter the content? If I need to implement them - can I only add a "Report" button in settings to report?
