I'm not a particularly big fan of Kid Rock, for a number of reasons. But he and a few artists had started doing things to thwart scalpers.

Namely, he'd announce tours slowly. And basically the strategy was that as scalpers bought out shows, he'd add another show in the same city. And keep doing that until there was no demand, no resale market, so scalpers were forced to sell at face or near face value. "I can keep throwing dates at you, and you're paying for the seats, so it doesn't hurt me, but no-one will buy them from you".

Eventually the scalpers learned to not, or minimally resell his tickets.
