A law passed six years ago in Tennessee that banned the use of software to buy event tickets in bulk and resell them at inflated prices has so far resulted in no prosecutions in Davidson County. Those who break the law must pay either $500 per ticket, or any profits made from each violation, whichever is higher; the ticket seller is designated the aggrieved party, and therefore must file charges. Factors complicating enforcement include refined software that scalpers use to breach computer systems that ticket sellers such as Ticketmaster employ, as well as jurisdictional issues when scalpers based outside of Tennessee target events within state bounds. Q Prime Management's Fielding Logan notes the lack of prosecutions is not limited to Tennessee. "It is a national problem," he says. "It crosses state lines. For a show in Nashville, it's not just people in Nashville buying tickets. So if somebody in California buys tickets and resells to a fan in Alabama, then who is the district attorney going after? Who is the enforcement entity in Tennessee? Are they going to fly to California and subpoena info on their server? It's never going to happen." Ticketmaster fights ticket bot use on two fronts, using its own programs and anti-bot software to revoke tickets when restrictions are violated as well as private litigation against organized scalpers.
