Maple Advisory Council

This, all by itself, represents way more investment than Nexon would ever put into this program. In my humble opinion.

If they were willing to spend time in forums and in-game (roflmao) they wouldn't need this "volunteer police" force.
And don't tell me "yes, but this is once and for all, not a continuous effort" - no, not really. First, you yourself write "series of elimination" which means trying and retrying. And then I expect a high level of attrition among the members, as with the MWLB before them. There are only so many "GM, he's ks'ing me, ban him!" (and the ensuing "He started it" "I've been here for hours" "I was born here and so was my father" "Ban him already!" "Sorry, I can't ban, but I have alerted a GM") a person can take before deciding this community isn't worth their time.
So every time one of your not-even-a-handful per server wears out, Nexon need to go scouting for someone new? Forget it. Might as well hire more GMs.

Not positive on this but GM's, and hopefully the "council" have the ability to look at previous chat within the channel.
