Valve has announced a record number of VAC Banned accounts for December 2018, across the range of games implementing VAC, including CSGO, DOTA 2 and Team Fortress 2.

The statistics for December show over 500000 accounts being banned, a number which is over 2.5 times the previous high set at 193000 in July 2018.

VAC, an abbreviation for Valve Anti Cheat, is a measure used by Valve to detect cheats in a players computer, like an aimbot or a wall hack. The player is permanently banned from playing the game, and their inventory is also seized by Valve.

Interestingly, CSGO observes the highest number of VAC Banned accounts every month, eclipsing games like DOTA 2 by a large margin, and has come under criticism by the community, which feels Valve have done little to improve the fairness of the game.

The largest VAC Ban since its inception can be attributed to CSGO being made completely free, thus motivating players to hack more frequently with the 15 dollar repurchase being removed.
