We want to prevent a situation where reddit is used more for moderation than the proper channels.
As you probably know, the reason these situations are not brought up in proper channels is the perception that those proper channels are useless. There's no feedback loop, and there are plenty of stories along the lines of "i reported the guy for griefing, but he's still not banned" (bonus, although slightly tangential: "permanans don't exist, look at this guy with 40 bans on his account drowning tanks yet again!")
It's borne out of frustration primarily. When the "proper channels" stop working (or are perceived to have stoped working) there's little recourse but to air your grievances in a public place. Such as reddit.
I agree our feedback loop for our reporting system is poor and has much room for improvement.
