Banned by Game Developer (Game Ban) Playing games should be fun. In order to ensure the best possible online multiplayer experience, Valve allows developers to implement their own systems that detect and permanently ban any disruptive players, such as those using cheats. You search the steam store with 'Valve Anti-Cheat enabled' and it'll return any game with it. You can click on 'single player' as well to lower the number down. Keep in mind though that single player games with mutliplayer will show up on that list if they have VAC. But again, VAC runs on the servers you connect to to play those games. One way to fix this issue is to manually install Easy Anti Cheat if for some reason it didn't automatically install itself (like with my game). Go to Program Files (x86)SteamsteamappscommonRising Storm 2BinariesWin64EasyAntiCheat and start the program EasyAntiCheatSetup.exe (this installation requires administrator access).

Valve Anti-Cheat, abbreviated to VAC, is an anti-cheat solution developed by Valve Corporation as a component of the Steam game development platform.

History
VAC was first released with Counter-Strike 1.4 in 2002,[1] following Valve's decision to forego PunkBuster in preference of a proprietary system. The initial version, VAC1, saw success for a period, but in March or April 2004 updates ran dry as the Valve engineers maintaining it moved on to the production of its successor, VAC2.
Valve does not normally discuss VAC, and very little is known about its internal workings. However, on November 17, 2006 they announced that 'new [VAC] technology' had caught 'over 10,000' cheating attempts in the preceding week alone,[2] the first real indication of the scale of anti-cheat operations. Not all of the accounts banned would have contained legitimate, purchased games, and there is no external audit on the figure.
As of 2010, unofficial sources estimate that over a million Steam accounts have been banned by VAC.[3][4]
Advantages
- Total integration through Steam, including using the Steam framework for any update tasks.
- Delayed bans deny cheat producers accurate and timely information. This causes a reduction in the supply of cheat programs to players who want to cheat online.
Disadvantages
A material hack, a type of content hack that is undetectable by VAC2.
- VAC cannot detect 'content hacks', where, for example, texture transparency and color are manipulated, since they do not involve modifying any program code. In Source engine games the option to create 'pure' servers (
sv_pure
) that prevent custom content from overwriting the game's defaults was created to alleviate this.[5]
Delayed bans, criticism & rationale
If a cheat is found the player's Steam account will be flagged as cheating immediately, but the player will not receive any indication of the detection. It is only after a delay of 'days or even weeks'[6] that the account is permanently banned from 'VAC Secure' servers[7] for that game, along with other games that use the same engine. (e.g. Valve's Source games, GoldSrc games, Unreal engine games). Valve never discloses which cheat was detected.
False-positive detections
There have been allegations that VAC has banned users for false positives.
- There are six recorded instances of incorrect detections, which were fixed and rescinded:
- VAC1: On its initial release, VAC would issue bans for faulty memory. Valve quickly updated VAC to only kick for faulty memory[8].
- VAC1: Running a VAC-protected game through the Cedega software compatibility layer for Linux.[9]
- VAC1: An apparent server-side glitch on April 1, 2004.[10]
- VAC2: Over two weeks in July 2010, approximately 12,000 owners of Call of Duty: Modern Warfare 2 were banned when Steam updated a DLL file on-disk after it had been loaded into memory by the game. Those affected received a free copy of Left 4 Dead 2 or an extra copy to send as a gift.[11][12][13]
- VAC2: In January 2011, owners of Call of Duty: Modern Warfare 2 or Call of Duty: Black Ops were banned due to their computers being infected by the trojan Win32/Spyeye.H.[14]
- VAC2: In June 2011, an unknown false positive detection caused a handful of Team Fortress 2 owners to become banned.[15]
- There are four recorded instances of game plugins that are not considered cheats triggering bans. These are:
- VAC1: HLamp, which allowed the user to control Winamp from the game's interface. Detection later reversed, and all bans caused by it rescinded.[citation needed]
- VAC2: The X-Spectate tool, which allowed server administrators to enable a wallhack effect while spectating to help decide if another player was doing the same. Later downgraded to a kick from the server, but bans not rescinded.
- VAC2: The single-player Half-Life modifications Paranoia and Half-Life FX, which made changes to the engine's renderer that propagated to multiplayer games. This still triggers a ban and no bans caused by it have been reversed.
- VAC and VAC2: sXe Injected, an anti-cheat system for Counter-Strike.
Cheats may be hidden inside otherwise legitimate mod or skin downloads that are created to maliciously get innocent people banned. Since the source of a cheat installed on a computer cannot be proven, bans due to this are never rescinded.[6]
Valve has 'a zero-tolerance policy for cheating and will not lift VAC bans under any circumstances.'[7] This includes account hijacking and other circumstances beyond the control of the account's owner.
Manually applied bans
In July 2010, several players who successfully used information leaked from Valve to increase their chances of finding a special Team Fortress 2 item called the Golden Wrench found themselves banned by VAC.[16][17]

To be fair, Steam numbers indicate that at least 10,000 cheaters get banned daily from Valve's digital distribution platform but they seem to have turned up the heat even further. This is basically providing in a day what you needed a week to get done.
The sudden nature of Valve's move has prompted many to speculate that the company's algorithms were updated to recognise previously undetectable cheat methods, which would indeed make sense. Well, either that or Steam's leadership took their sweet time to be certain.
The sheer scope of Steam's digital offer means that VAC had plenty of games to cover, although it doesn't take a psychic to assume participation by the usual in-house suspects like Counter Strike: Global Offensive, Dota 2 and Team Fortress 2. We can't forget third-party games either, with Call of Duty perhaps being the prime example of Steam's third-party heavyweights. Online game cheats wizard101.
We're sure there are plenty more games targeted though but it's not like we discriminate when it comes to cheaters - we hate them all the same.
As these things usually go, reddit has responded as well by opening a subreddit dubbed , which isn't dedicated to porn but the banned cheaters. Many players are recognising old, ahem, acquaintances. Others are simply taking pleasure in the fact that many of these Steam accounts have some serious bling in their inventory, with one account having tens of thousands of dollars.

Incidentally, in what are more coincidental than correlated news, Niantic have tightened up their Pokemon GO as well, introducing a three strike policy with an appeal period. Obviously, not even Pokemon are exempt from people looking to ignore the rules and just end up first, however they would justify it in their heads.
