The day after the sale closed on 6 July, Valve banned over 40 000 accounts on Steam, the largest number the developer has ever suspended at once. It eclipses the previous record of 15,227 from October 2016.
Nobody likes cheaters, so raise a glass this evening to the VAC team. They then create multiple accounts and use them to test which hacks can be detected by the VAC system. All I do know is that cheating isn't cool, and Valve seems to feel the same way.
A couple days ago, Valve went through and made a whole bunch of Steam bans. VAC bans are also permanent and non-negotiable, so if Valve swings its banhammer in your direction, you can pretty much say goodbye to playing multiplayer games in a lot of popular titles. That's just one possibility, and it's unlikely that Valve is going make any statement about this massive wave of bans.
Users cheating isn't the only worry that the staff at Valve have on their minds as earlier this year the CS gaming community on Steam was plagued by a chat bot invasion in Counter-Strike: Global Offensive.
A further 4,972 accounts were banned as a result of in-game reports, for a total value of lost skins and other digital items of up to $9,580. This happened on June 6, when other players reported the cheaters in-game. Each time someone is caught cheating on Steam, it ends up costing Valve money.
Apart from those VAC bans, 4,972 more users were banned.
