Pro Counter-Strike depends on fans trusting that every match is real. That trust is protected by match fixing rules, cheating rules and the bodies that enforce them. This guide explains how esports integrity works in CS2, who investigates problems, and what past cases teach. It is about how the system works, not legal advice.
What counts as match fixing?
Match fixing means deliberately changing the result of a match, or part of it, for a reward. The reward is usually betting profit. It can be as obvious as throwing a game, or as small as losing a set round or a pistol round on purpose.
Related offences include:
- Betting on your own matches: banned by most rulebooks, even if you bet on your own team to win.
- Sharing inside information: passing line-ups, injuries or plans to bettors.
- Cheating: using software or exploits to gain an unfair edge.
- Leaking strategies: giving a team's private plans to rivals.
Each organiser writes its own rulebook. The details differ, but these core ideas show up almost everywhere.
Who enforces match fixing rules?
There is no single global regulator. Instead, several groups share the job.
The Esports Integrity Commission (ESIC)
ESIC was founded in 2016 as the Esports Integrity Coalition, and took its current name in 2019. Its founder, Ian Smith, was a former sports regulation lawyer. ESIC investigates match fixing, cheating and doping. It works with tournament organisers and betting companies, and those partners enforce the sanctions it recommends.
Tournament organisers
Organisers run the events and apply the rules. They can disqualify teams, strip prize money and ban players from their own events. They usually honour ESIC sanctions if they are members or partners.
Valve
Valve controls the Majors. It can bar players from events it sponsors, separately from any ESIC ruling. Valve also runs VAC, its anti-cheat system, for matchmaking. Our guide to CS2 anti-cheat covers that side.
Case study: iBUYPOWER, 2014
In August 2014, the North American team iBUYPOWER lost 16-4 to NetcodeGuides.com, even though iBUYPOWER were heavy favourites. A tip to Dot Esports later showed the match had been fixed. It is often called the first large match fixing scandal in CS:GO.
Valve responded by banning seven players from its Majors. According to Wikipedia, the ban effectively ended the top-level careers of several players, including two of North America's best in-game leaders. The message was clear: fixing even one match could end a career.
Case study: the 2020 coaching bug
In 2020, investigators found that some coaches had abused a bug in spectator mode. In some cases it let a coach see parts of the map they should not have been able to see. ESIC sanctioned more than 37 coaches. Valve also punished coaches at its Majors, with the length depending on how often each coach used the bug.
The case shows that integrity rules cover more than betting. Using a known bug for an advantage is treated as cheating. Our article on CS2 coach rules looks at what coaches are allowed to do today.
Other notable cases
- In August 2021, ESIC banned the coach HUNDEN for leaking Heroic's strategy folder during IEM Cologne 2021. ESIC lifted the two-year ban early in December 2022.
- Before PGL Major Antwerp 2022, ESIC banned the Team Spirit coach for a minor 2020 coaching bug offence. The ban was overturned soon after the Major, which drew criticism.
How can you report suspicious activity?
If you see something suspicious in a pro or amateur event, report it to the organiser first. Organisers that work with ESIC can pass serious cases on to it. For cheating in your own matchmaking games, use the in-game report tools covered in our guide to reporting cheaters.
If you play in amateur events, read the rulebook before you start. Never bet on matches you play in, and never share private team information. Even small breaches of match fixing rules can lead to long bans.
