The Mitigating Automated Internet Networks for Event Ticketing Act, or MAIN Event Ticketing Act, significantly strengthens consumer protections in online ticket sales by expanding the scope of the Better Online Ticket Sales (BOTS) Act of 2016. It explicitly prohibits the use of automated applications that circumvent online ticket purchasing rules, access control systems, or other security measures implemented by ticket issuers. A central provision mandates that online ticket issuers implement and maintain robust security safeguards for their websites and services, including systems to enforce purchasing limits. These safeguards must protect the platform's security, confidentiality, and integrity, with requirements extending to third-party service providers. Issuers are also obligated to regularly update their security measures in response to evolving threats and business changes. The bill further requires ticket issuers to report known circumvention incidents to the Federal Trade Commission (FTC) within 30 days and to take reasonable steps to address these vulnerabilities. The FTC will establish a public website for consumer complaints and share relevant information with State attorneys general. Violations of these provisions will incur substantial civil penalties, starting at $10,000 per day or $1,000 per violation, with enhanced fines for intentional infractions. Additionally, the Act promotes coordination among federal and state law enforcement agencies, including the FBI and DOJ, to share information about cyberattacks targeting ticket issuer security systems. The FTC is also directed to publish guidance for ticket issuers on compliance and to report to Congress on enforcement efforts and any identified limitations.
