"It's not botting, it's AFK training"

I get the vibe that not everybody knows what the OP is referring to. It's a "glitch" that's been around for a long time now. I think it involves key down attack skills while alt-tabbing out of the game (maybe its with windowed mode, dunno I never use windowed mode), and your character will continue to attack while you are not actively playing the game... Essentially letting players bot without using 3rd party software. This is where the "Spin4Days" slogans come from (for those who aren't aware).

I would like to assume that Nexon knows about this (its quite old), but they don't seem interested in doing anything about it. Maybe they don't know how much it's being used by players trying to climb the ranks?
