In speedrunning, "any% glitchless" runs often use Protohax techniques (clipping through walls via frame-perfect inputs). The community accepts these because they are "in the code." Protohax takes this logic to multiplayer, where the human opponent becomes the victim of the code’s literal interpretation. A player using a standard mouse achieved zero recoil on an R-99 SMG. Anti-cheat (EAC) did not ban him. Why? Because he wasn't cheating.
He was using a : a script that vibrated his mouse at 15Hz horizontally while firing. The game’s recoil compensation algorithm (designed to smooth controller stick drift) interpreted the vibration as intentional correction and zeroed out the vertical climb. protohax
We assume that pressing "W" moves us forward. Protohax demonstrates that pressing "W" sends a suggestion to a physics engine, which then negotiates with a server, which then renders a frame. Every negotiation point is a potential Protohax vector. In speedrunning, "any% glitchless" runs often use Protohax
