Cheating in Esports: The "Coach Spectator Bug" Decision


Esports is an umbrella term which describes the world of competitive, organised video gaming. On 29 September 2020 the Esports Integrity Commission (ESIC) suspended 37 individual Counter Strike: Global Offensive (CS:GO) team coaches arising from the ‘Spectator Bug Abuse’ investigation (coach spectator bug decision). Many of these high-level coaches admitted to abusing a bug in the spectator mode to give their teams an unfair advantage in matches. 

The role of the coach bug

Like traditional sports, the coach is an integral part of an esports team, both in and out of competition. During esports competitions, coaches will observe their players live. However, the coaches are limited to observing their own players and cannot see the opposing team players, which if permitted would give them an unfair tactical advantage. 

CS:GO’s “coach bug” allowed the game to be manipulated so that the coach had an unrestricted camera view anywhere on the map, which allowed them to see the opposing players’ locations and how they were playing, providing the coaches with an opportunity to optimise their team’s strategy. They then relayed this information to their own team to give them an unfair advantage.


Using bugs to gain an unfair advantage in play is deemed to be cheating by ESIC and ESL (a major esports tournament organiser). ESIC’s disciplinary offences are broken down into four levels, with “Level 4 Offences” being the most serious.
In this case, ESIC found that all of the coaches’ offences were Level 4 Offences. The behaviour of three coaches were found to be in breach of Articles 2.3.3 and/or 2.4.4 of the ESIC Code of Conduct “Cheating or attempting to cheat to win a Game or Match.” It was held that these breaches were of the most serious, resulting in suspensions ranging from six and a half months to 36 months. Together with bans of the same length from ESL competitions, ESL also retrospectively disqualified the relevant teams from the tournaments, rescinded previously earned ESL Pro Tour points and retrieved prize money.

Esports in Ireland

The Esports and Gaming Federation of Ireland (Ireland esports) was recently established and now operates as the official governing body for esports in Ireland. In general, esports are considered to be a competition under Irish law. While there are no specific Irish laws regulating esports competitions, consumer protection and data protection laws are of particular relevance to competition organisers involved in a competition operated from Ireland or provided to consumers in Ireland. 

Key takeaways 

With the emergence of the esports industry, arguably its greatest challenges are the lack of a recognised governance system and the absence of industry assurance models across all areas of esports from league structure, rules and player/team contracts, to marketing and promotion, prize pool funds and live streaming. 

Prevention of cheating presents its own unique challenges for esports regulators and tournament organisers. While COVID-19 enforced restrictions have resulted in a huge growth in esports participation, it appears that the exploitation of the ‘Spectator Bug’ was primarily facilitated due to the fact that the competitions were held remotely, rather than in person. By imposing sanctions, ESIC has taken positive steps to curtail the potential for cheating. 

The coach spectator bug decision will be of interest to Ireland esports, as the official governing body, and to other parties involved in the emerging esports market in Ireland, such as AeonSpark Events, Ireland’s newest Dublin-based gaming event company. The coach spectator bug decision will also be of interest to Phelan Gaming, Ireland’s most successful esports team and their new partnership with Munster Rugby, now rebranded as Munster Rugby Gaming.
