(NEXSTAR) – The Federal Trade Commission (FTC) and attorneys general from seven states are suing Ticketmaster and its parent company for allegedly profiting on fees while turning a blind eye to widespread, illegal resale tactics.

The complaint accuses California-based Ticketmaster and its parent company, Live Nation, of duping artists and attendees with low advertised ticket prices and claims of strict ticket purchase limits, "even though ticket brokers routinely and substantially exceeded those limits." Customers were then forced to buy the same tickets on Ticketmaster's resale platform at a "much higher cost," the suit says.

One internal review found that just five brokers were in control of 6,345 Ticketmaster accounts and had 246,407 concert tickets to 2,594 events, according to the FTC.
