So Valve recently announced that they've started using a new "Anti-Cheat" system..
Pretty much given up on VAC.
Valve started using an A.I that will learn and ban cheaters by reviewing every single demo of every single match.
http://www.pcgamer.com/valve-wants-to-take-a-machine-learning-approach-to-counter-strike-anti-cheat/This means that Spin botters will obviously get banned right away as the A.I must know if this person if spinning constantly they're cheating, but this leaves a massive hole.
People who use AFK script might also get banned for cheating and not griefing, good players with fast reaction time or playing purely based on good game sense and sound might suffer from this, cheaters who hide their cheats by not prefiring will surpass the A.I, what do you guys think?
Personally I've seen it being effective as in Emirates servers right now since the implant of this I've only played against TWO cheaters in a week which both of them got "Account has been convicted" mid game.
BUT, this will only stop cheaters in Official MM Servers.
So this shows that valve doesn't really care about other tournament hosters but mostly about majors as during majors they will be playing on official valve servers.
