The Mitigating Automated Internet Networks for Event Ticketing Act, or MAIN Event Ticketing Act, aims to significantly strengthen the existing Better Online Ticket Sales (BOTS) Act of 2016. Its primary purpose is to improve online ticket sales and enhance consumer protection by combating the use of automated bots to unfairly purchase event tickets. The bill expands the definition of prohibited acts to explicitly include using applications that perform automated tasks to circumvent an online ticket issuer's access control systems, security measures, or other technological controls designed to enforce purchasing rules. A key provision requires online ticket issuers to establish, implement, and maintain robust access control systems and security measures to enforce posted event ticket purchasing limits. These issuers must regularly evaluate and adjust their safeguards in response to technological changes and evolving threats. Furthermore, they are mandated to report any known incidents of circumvention to the Federal Trade Commission (FTC) within 30 days of discovery and take reasonable steps to address the underlying causes of such circumvention. The bill directs the FTC to create a publicly available website for consumers to report violations and to share these complaints, along with issuer reports, with State attorneys general. The FTC is also tasked with publishing guidance for online ticket issuers on compliance within one year of the Act's enactment. Importantly, the legislation clarifies that FTC guidance does not create new rights or bind the Commission, and enforcement actions must be based on specific violations of the Act itself. To deter illegal activity, the MAIN Event Ticketing Act significantly increases civil penalties for violations, imposing daily fines and additional penalties per violation, with enhanced penalties for intentional breaches. It also establishes a framework for improved coordination among the Federal Bureau of Investigation, the Attorney General, and other law enforcement officials with the FTC to share information regarding cyberattacks on ticketing security measures. Finally, the FTC is required to submit an annual report to Congress detailing enforcement actions and any limitations encountered.
