Can Thailand esports star face criminal charges for cheating at SEA Games?

Warasin, known by her in-game nickname Tokyogurl, was disqualified from the 33rd SEA Games and received a lifetime ban from the organizers after being found guilty of severe technical violations.

According to Thaiger, the scandal raised questions about whether she could face prosecution or even imprisonment. The common answer among many experts is that cheating using unauthorized software in esports typically results in administrative penalties like disqualification, medal stripping and bans, rather than jail time.

These punishments fall under the jurisdiction of sports federations, not the criminal courts, so they do not constitute grounds for imposing sentences.

Legal liability only arises if the cheating satisfies specific criteria under Thai criminal statutes. One of them is the Professional Sports Promotion Act, which targets match-fixing and the manipulation of results.

Criminal prosecution under this act requires proof of bribery or betting-related financial gain. If the cheating was motivated solely by a desire to win, without evidence of financial transactions, this law is unlikely to apply.

Another approach is the Computer Crime Act, which requires technical evidence that the accused illegally accessed, attacked or damaged the tournament’s central server system to be prosecuted. Installing assistive software on a personal device is not sufficient to meet this threshold.

However, lawyer Monchai Jongkairattanakul offers a different legal perspective. He argues that if an athlete intentionally conceals cheating to obtain benefits, such as prize money, bonuses or medals, the act could technically constitute fraud, with a potential prison sentence of up to three years.

According to this analysis, while professional sports regulations typically apply to match-fixing, cheating to win may be considered deceiving the organizers or the public.

The lawyer also warned that teammates who were aware of the cheating but remained silent could be considered accomplices according to the law.

In this context, the decision to withdraw the team from the tournament may have been a strategic measure to avoid further legal exposure should they go on to compete and win.

Tokyogurl’s punishment currently stands at a lifetime ban, with no indication of criminal prosecution. Experts believe this serves as a clear warning to esports athletes: the line between violating competition rules and breaking the law is very thin.

Reporting misconduct when detecting signs of cheating not only protects the transparency of the tournament but also allows individuals to avoid the risk of criminal liability, which is more scathing than being banned from competing, they said.

Tokyogurl, the marksman for the Thailand women’s Arena of Valor (RoV) team, was found to have violated the Esports Technical Code by using unauthorized third-party software or interfering with and modifying competition equipment during a SEA Games match against Vietnam on Dec. 15.

On Thursday, TESF president Santi Lothong confirmed that the person who played on Tokyogurl’s behalf during the SEA Games 33 has been identified. According to him, there is clear technical evidence, from monitoring in-game behavior to the use of Discord to share screens and control the game, with two accounts logged in simultaneously, Sanook reported.

The organizing committee's IP system was set up for monitoring, but the player's actual IP was from a different network, allowing the federation to track down the individual. Lothong stated that the person is a semi-professional player with high gaming skills, but their name has not been revealed yet, as the organizing committee is still considering the legal aspects.

Lothong emphasized that the federation will conduct a thorough investigation to see if anyone else is involved and to restore the reputation of Thai esports. Any violations, if discovered, will not be overlooked, he said.
