Could also be cosmic rays. Or ghosts.

But I imagine they tested the patch, like any other patch, and did not find evidence of any other access to that memory. You can never be 100% sure, but if that’s the standard, then how could any banned player be 100% sure cheat software wasn’t secretly installed on their system using nation state invisible rootkit capabilities?

Cosmic rays can be excluded by sampling. Say, someone triggering a guard page once or twice gets ignored, but consistent read activity whenever the user is playing is likely to be either an antivirus (which can be correlated and culprits identified) or a cheat.

You haven’t ruled out ghosts.

Haunted players are either using that to their advantage or cursed. Do you really want to interfere with a curse? I certainly wouldn't, too much risk of it getting transferred to me.
