Spec request: Allow reporting of invites to the originating server

[MTRNord]

Suggestion
A way to report an invite to the originating server as spam. Probably combined with the inviting user.

This is especially useful for invite spam coming from matrix.org.

A later advancement of this may be servers requesting that the originating server doesnt allow invites from the originating server to the target server between user A and B.

Fixed by matrix-org/matrix-spec-proposals#4151 - the whole room can now be reported. Client implementation appears lacking at the moment, but the spec side is done.

I believe this issue isnt yet finished as I am asking for reporting it to the originating server and explicitly mention matrix.org as an example. I would argue matrix-org/matrix-spec-proposals#3843 is required for this issue to be closed.

If a room is reported, then the inviting user from a spam invite wouldn't be reported along with that, correct?

For the case where invites to a legitimate room are spammed, room reports definitely don't resolve this issue.
