You'd be surprised to know that this strategy works quite well! Pixel bots require a hardware fake display when faced with kernel anti-cheat. They also depend on color/pattern recognition, as AI is not yet capable of operating at the frame rates required for competitive games. That allows the bait to be seen by a bot, but invisible to the eye.

If you are successfully baited and detected, you also get HWID banned, so it only takes once. This makes cheating via pixel bot unviable.

On the contrary, DMA is so desired because it eliminates this risk.
