Commenting on rule violation
It does nothing - it's just an info for other voters (and maybe the host). Some host reply to such messages, some ignore them.
It would be much better to contact the host directly (by clicking on the host's name on top of the challenge).
But even this will not guarantee that anything happens.
It would be even better to lodge a complaint using the Complain button . . . that is what it is for, and let the Host know about the invalid entries. The Host can then decide to enforce the rules . . . or not.-- hide signature --

My complain button is out of service for a very long long time. It is flashing TILT ! An it is screaming: Nobody's at home!
