Senator Chuck Schumer announced that he plans to introduce a bill to the Senate to make the use of online ticket-buying bots a federal crime.

The bots are software utilized by individual people or companies to buy a large quantity of tickets online, which are then sold on different websites for more money.

Schumer’s actions are partially promoted by a recent Bruce Springsteen concert in Rochester, when tickets to see the artist at Blue Cross Arena were listed for as much as $5,000.

At a press conference, Schumer said, “We got a whole bunch of calls to our office from Springsteen fans who were outraged.”

According to the Democrat and Chronicle, Schumer himself was also outraged by the bots, saying that local venues are the only opportunity many residents ever have to see world-class acts like Springsteen in Rochester and Paul McCartney in Buffalo. Indeed, just like most customers live within a five-mile radius of a business, most attendance at such concerts is local.

Openly enraged, Schumer declared the bot operators “nefarious bottom-feeding people who take people’s joy away.”

The proposed bill, dubbed the Better On-Line Ticket Sales Act (BOTS Act), has already come before Congress and was sent to committee in March 2015. Schumer noted that there is widespread support from the whole industry, especially since the bill doesn’t penalize platforms used to sell the tickets.

Under the bill, federal authorities would be able to track down anyone using bots and issue fines of $16,000 per ticket, per day.
