Making Pure Mesos in MapleStory

This. The only issue I can think of is it would be really difficult to survive first starting out without meso drops to buy pots and such.

An easy solution to this would be for new characters to get meso drops (perhaps 2-3x meso, since the mesos dropped by low level mobs is practically nothing and isn't really enough to buy pots with). When a character reaches level 60, everything stops dropping meso. This should allow for enough meso gain to buy pots, but make it much less worthwhile for botters to bother trying.

There's a setting for botting programs to auto suicide, to not overlevel if the person is farming a certain item or botting a certain map with desirable drops. This only hurts legits, much like the decreased drop rates which were added as a "countermeasure." Nexon needs to acknowledge the problem that there is a huge base of hackers and needs to fix their security... Instead of applying bandaids to a freaking amputated limb of a game.
