The Structure of Scandals in the SNS Era
Since the 2010s, the spread of Twitter and Instagram has created an environment where NPB players' private behavior can go viral in an instant. Previously, scandals originated from weekly magazine reports, giving teams some ability to manage information in advance. In the social media era, however, posts by players themselves or eyewitnesses spread in real time, often leaving teams scrambling to respond. In 2016, a young player on a certain club posted an inappropriate late-night video to his Instagram story, and screenshots spread on Twitter, reaching tens of thousands of retweets within hours. The club held an apology press conference the next morning, but online criticism had already erupted. This incident demonstrated to the baseball world that SNS-era scandals unfold at an entirely different speed and scale than traditional ones.
Notable SNS-Related Incidents
Multiple SNS-related incidents have been documented in NPB. In 2017, a pitcher posted a tweet mocking an opponent after a game and received a formal reprimand from his club. In 2019, a college player considered a draft prospect reportedly had past discriminatory tweets unearthed, allegedly leading teams to avoid selecting him, illustrating the problem of digital tattoos. In 2021, photos of several players dining together during COVID-19 stay-at-home advisories leaked on social media, resulting in game suspensions. In MLB, Josh Hader's past racist tweets surfaced in 2018 and became a major controversy, showing that SNS risk is a shared challenge across Japanese and American baseball. The NPB Commissioner's Office requested all clubs to establish SNS guidelines in 2020, and all twelve teams had adopted their own social media policies by 2021.
Team Countermeasures and Media Literacy Education
Teams have incorporated SNS literacy education into their rookie orientation programs. The Yomiuri Giants have invited external crisis management consultants since 2019 to conduct biannual workshops. The Fukuoka SoftBank Hawks require players to sign a social media usage pledge upon joining the organization. Training covers topics ranging from pre-posting self-check procedures and disabling location sharing to understanding the risk of screenshot-based dissemination. At the same time, a player's personal reach on social media is a marketing asset. Players like Kodai Senga (then with SoftBank) and Yoshinobu Yamamoto (then with Orix) used social media to build closer connections with fans, positively impacting merchandise sales and sponsorship deals. For clubs, balancing risk management with leveraging players' influence has become a key business challenge.

Future Outlook and Emerging Challenges
As social media platforms diversify, the nature of risks continues to evolve. The rise of video-centric platforms like TikTok and YouTube Shorts has increased the risk of controversies involving visual content, not just text. Additionally, advances in generative AI and deepfake technology pose new threats, including the spread of fabricated videos or statements impersonating players. NPB placed AI-generated content response policies on the agenda at its 2024 owners' meeting. Overseas, the Korean Baseball Organization (KBO) partially introduced a system in 2023 where team PR departments pre-screen player social media posts, though this sparked debate over freedom of expression. In NPB as well, building a framework that respects players' rights while protecting the league's overall brand value is an urgent priority.
Fan Communities as Aggressors and Vigilante Justice
An often-overlooked aspect of SNS-related incidents is the structure in which fan communities themselves become aggressors. When a player's careless post is discovered, responses escalating beyond criticism into vigilante punishment have occurred repeatedly. This includes doxxing, where personal information of players' families or partners is identified and exposed, harassment calls to restaurants frequented by players, and concentrated torrents of abuse directed at official team SNS accounts. These acts constitute social problems separate from the player's original misconduct and may incur legal liability for defamation or obstruction of business. Team legal departments find themselves occupied responding to such excessive vigilante behavior. Meanwhile, suppressing critical fan voices altogether is difficult from a freedom of expression standpoint, and drawing a clear boundary between legitimate criticism and vigilante punishment remains a challenge for the entire baseball industry.
Retired Players and Continuing SNS Risks
SNS risks do not disappear upon retirement. Cases in both Japan and the United States have been reported where former players made inappropriate remarks on SNS after retirement, resulting in analyst contracts being terminated or coaching career prospects being damaged. In MLB, there have been cases where former players made discriminatory statements on podcasts or social media, reportedly affecting Hall of Fame voting. In NPB as well, past SNS posts may become subject to review when former players seek to return as coaches or front office staff. Even more serious are cases where retired players facing financial hardship become involved in fraudulent investment solicitation or information product sales through SNS. Such conduct exploits the credibility attached to the title of former professional baseball player and damages trust in the entire baseball world. The NPB Players Association incorporated SNS risk management courses into its second-career support program for retired players starting in 2022.
International Comparison - The Spectrum of Regulation and Autonomy
The regulation of player SNS usage varies widely across countries and leagues. MLB has a strong culture of valuing individual player brand building and officially imposes no comprehensive SNS restrictions beyond prohibiting posts during games. The fundamental approach is individualistic, with players taking responsibility for their own statements. In contrast, the Korean KBO introduced a pilot system in 2023 in which some teams review posts before publication, stepping into territory that restricts players' freedom of expression. NPB occupies a middle ground between the two, adopting a self-regulatory model that relies on team-specific guidelines and education. The Australian Baseball League (ABL) incorporates SNS clauses into a league-wide unified code of conduct, with graduated penalties for violations explicitly documented. Each approach has its merits and drawbacks, and no universal solution exists for balancing players' freedom to communicate with organizational risk management. Each league's decisions are deeply rooted in the history of labor relations and legal frameworks regarding freedom of expression in their respective countries.
