[Standards] Re: LAST CALL: XEP-0377 (Spam Reporting)

I'm planning to implement that XEP in Monal as soon as reporting messages/ users in channels is somehow covered by the XEP. I had even already started to implement it, when I realized that the reporting element isn't defined for my channel moderation usecase at all.

You want moderators to use it to report to the server that the spam originated from? Or you want participants to use it to report to mods of the channel (ala "flag this message" buttons).
