On “Valve secrets spill over in new Steam documentary app”

If you're interested, Valve uses deep learning model called VACnet to "watch" every player on their servers01. If any dodgy gameplay is detected, it gets submitted into a moderation queue called Overwatch2, which is basically delegates the decisions to ban cheaters community. It's really cool how they've gamified this. 0 link 1 link to this video 2 link

On “EA is permanently banning Linux players on Battlefield V”

There exist good solutions, but none of these companies have the competence or will to actually solve the problem. It’s security theatre a la malware. “Hey everyone install this rootkit to pretend like we’re preventing cheaters. Don’t worry about the keylogging and screenshot uploading.” What’s most surprising is that the vast majority of gamers aren’t outraged by this at all, despite repeated demonstrations of untrustworthiness by anticheat companies. link to this video

On “Valve Steam Deck”

link to this video Valve is already using machine learning to analyze player mouse movements across all games to look for "inhuman" patterns and send those directly to the community-staffed manual review process called overwatch.

…se movement or in Dota clicking out of regular camera bounds to detect these cheaters and expedite them to the Overwatch queue. You can readily download the biggest script client for Dota 2, and VAC ban waves for using it have been unheard of for years now (you only get an in-game ban when enough other players verify the cheating via Overwatch). link to this video link…

On “The Day Windows Died”

That's not what I said - my point is that companies with a relaxed security baseline (ie. not having a dedicated team of people tasked with investigating cheats and improving their anti-cheat system) tend to invite an increased number of cheaters into their games, and I back this up with real events. - These companies will send cease-and-desist letters to cheat makers instead of working to detect their cheats (Joduska.me ceased operations due to a Riot C&D, and Bossland GmbH was actually sued and lost). If these cheats were instead detected and users banned on a continuous basis, no lawsuits would be needed. - CS:GO implemented (as in, almost a decade ago) an "Overwatch" review system to all…
