Consumer protection: other; certain uses of automated programs to purchase event tickets online; prohibit. Creates new act. TIE BAR WITH: HB 4262'25

SB 158 prohibits the use of automated programs (bots) to purchase event tickets online in bulk. It directly affects consumers trying to buy tickets fairly and venues or ticket sellers using such bots to manipulate sales. The bill creates a new legal prohibition against these automated ticket-buying practices, making it illegal for businesses to deploy them. This policy change aims to prevent scalping and ensure equitable access to tickets for the general public.
