Congress passed a bill yesterday that will make it illegal for people to use software bots to buy concert tickets. Ars Technica reports: The Better Online Ticket Sales (BOTS) Act makes it illegal to bypass any computer security system designed to limit ticket sales to concerts, Broadway musicals, and other public events with a capacity of more than 200 persons. Violations will be treated as "unfair or deceptive acts" and can be prosecuted by the Federal Trade Commission or the states. The bill passed the Senate by unanimous consent last week, and the House of Representatives voted yesterday to pass it as well. It now proceeds to President Barack Obama for his signature. Computer programs that automatically buy tickets have been a frustration for the concert industry and fans for a few years now. The issue had wide exposure after a 2013 New York Times story on the issue. Earlier this year, the office of New York Attorney General Eric Schneiderman completed an investigation into bots. The New York AG's ticket sales report (PDF) found that the tens of thousands of tickets snatched up by bots were marked up by an average of 49 percent.
