+Reporting Content
+=================
+
+.. _module:report_content:
+
+Users may encounter content which they find inappropriate and should be able
+to report it to the server administrators or room moderators for review. This
+module defines a way for users to report content.
+
+Content is reported based upon a negative score, where -100 is "most offensive"
+and 0 is "inoffensive".
+
+Client behaviour
+----------------
+{{report_content_cs_http_api}}
+
+Server behaviour
+----------------
+Servers are free to handle the reported content however they desire. This may
+be a dedicated room to alert server administrators to the reported content or
+some other mechanism for notifying the appropriate people.
