I guess what I’m saying is if this information was being sent across a network, that would be detectable.
If you are constantly monitoring 24/7/365, sure. We don’t know how often it would send it if it does, it would require reverse engineering and intense monitoring. Also, even if they aren’t doing it now doesn’t mean they can’t easily add it in a patch.
It’s generally not worth trusting IMO.
Except drivers are designed to interact with hardware and to make it usable, kernel-level anticheats are designed to specifically scan/block/etc software. They are pretty different with their intended purposes, even though they offer the same/similar invasiveness.
