> Even Valve Anti-Cheat (VAC) which is considered by many to not be very intrusive, used to intercept DNS queries to detect communication with paid cheats DRM.

I was surprised hearing this. It seems like what they actually did was if VAC already found something, it checked the hashes of the contents of the DNS cache against a list as a second check. That's quite a bit different from "intercepting DNS queries".

Overall VAC always made a reasonable impression on me as far as privacy and security are concerned (no SYSTEM services, no kernel driver, no screenshots, no scanning and uploading random files etc.), although this non-intrusive approach naturally limits the kinds of cheats it is able to discover. I feel like the approach taken by Vale is, on the whole, well balanced.

Yes, thanks for clearing up the intercept part, I didn't remember how they did it exactly. They do make right decisions in my opinion to balance security/privacy issues at the cost of less ability to detect cheats. I think they also have a pretty good record of not banning inocent people.
