While the downvote is effective to a point, I think there should be a better method to report threatening comments besides PMs which are the same stream of information as Feedback, questions, etc. Having a report button would be easy, reasonable on mobile, and would be sent to its own area where threatening comments could be dealt with expeditiously.

I feel like once this website gets to be much larger that sort of system would just be ineffective. (not the downvote system but the general account to handle all grievances).
