Thanks to PC Gamer, and a bit of help from Twitter, we have some insight. First off, let me start by telling you that rumours have been floating around recently relating to Valve supposedly having some Counter-Strike professionals arrive at their offices for some secret meetings and such. That’s old news, or rather, old rumours.
Half-Life and Portal writer Erik Wolpaw has detailed how his team has been using Generative AI for research and development at Valve.

Counter-Strike 2 dev Ido Magal confirms that 960,000 accounts were VAC banned from the FPS in its ongoing clampdown on CS2 farming bots.
i mean thats a problem of their own design to begin with, but because it makes them so much money they won't change it. It's something that they at least ban a bunch but it's the absolute minimum that they're doing.
Must be a lot of inactive accounts, there's no discernible difference in the active player count on the Steam charts.
