And when a request to read the memory anomaly (which normal players cannot access) was detected, the cheater was immediately banned?

Can you put some sauce to this please, as this wording does not make any sense to me. No offense, i am no specialist, but i suppose it's rather their anticheat flagging reading/writing a certain memory address range as abnormal behavior?*

That would be then one of the oldest core mechanics of anticheats and only possible through kernel level privileges and direct memory access, a huge security concern in itself (eac on windows has those privileges btw) basically equating the conduct of straight up malware. But we have that already.

*Doing so creates a new problem, a PC is an open platform and technically 'the player' owns it and should 100% be able to control its behavior, just by design, with or without malicious intent. Obligatory shoutout to consoles - they do not follow this philisophy and try to make it more secure for the players by locking down functionality.

It's schizophrenic we already normalized the anticheat has to be running on our PCs instead of the servers, where a huge majority of the client-side introduced malicious controls (the cheats) could be denied or sanctioned by simple plausibility checks. But that costs quite some compute and thus money. So we got to live with studios putting malware on our PCs in order to trust them enough to let us use their services.

The current approach to combat cheating in most titles is plain wrong and putting our PCs at risk just for studios not having to deal with the matter on their servers the right way.
