If this is real, you'd hope for Ticketmaster to come in clean and purchase it back.
Maybe worth pointing out- that's a feature, not a bug.
The value Ticketmaster provides is taking the anger from fans for high prices. The performers (and producers/labels/whatever) want to extract as much value from their fans as they can, and having Ticketmaster look like the greedy badperson prevents their fans from being mad at them.
