Fingerprinting that is that hyperspecific is the one that’s actually flawed. If you could circumvent a hardware ban by rearranging your RAM sticks, it wouldn’t be much good.
As it is, the CPU is the one most stable, expensive, and difficult piece to replace, so it makes sense to ban on that alone.
But, I do agree that cheaters are really slimy fuckers, so what you’re saying is certainly possible. I remember a kid that had his grandmother bring his computer into the shop to see we could evade his hw ban, talked his grandmother into agrreing to buy him a new GPU right in front of us before we turned him down flat.
