Southperry's MapleGuide Program!

It's more due to their presence that eliminates people, not their actual banning skills.

I mean, what hacker wouldn't be scared of someone that can turn invisible and teleport across the Maple World?

None of them apparently, since GMs have both those powers plus the BanHammer but weren't accomplishing anything. The aveage hacker is going to know that all the Guides can do is stalk them invisibly and spam reports that the same GM staff that hasn't done squat historically will continue to ignore today.

It's entirely up to the GMs to make this work, because no amount of guides is going to accomplish anything if the reports aren't acted on.
