The Federal Trade Commission accused a shadowy group of flooding Ticketmaster with fake accounts to purchase and resell tickets to concerts by Taylor Swift, Bruce Springsteen and other top artists.

The FTC lawsuit claims the reseller used fake accounts and banks of SIM cards to snag over 379K tickets from Ticketmaster in just over a year.

Ticketmaster came in for heavy criticism after fans complained of faulty technology and eye-watering prices for 2022 sales for Taylor Swift and Bruce Springsteen’s tours.
