Reporting 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".

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.

The server MUST verify that the user has permission to view the event before accepting a report.
