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.

{{< changed-in v="1.8" >}} The server MUST verify that the user reporting the event is currently joined to the room the event is in before accepting a report.
