I find these to be weasel words.
I don't use Ticketmaster. Full stop.
If your concert uses Ticketmaster, I'm not going to that.
It's not a problem because all the cool acts don't use Ticketmaster. Only lame old decrepit acts use Ticketmaster anyway. And if I wanted to see those, I'd go to Vegas, and at least get a comped all you can eat buffet as well.
Brown Paper Tickets is an alternative that is fair and reasonable. Oddly, many fantastic acts I've see such as The Orb use them for ticket sales instead of the vile corrupt corparate boondoogle that is Ticketmaster.

Ticketmaster was corrupt and horrible 30 years ago. If you are still using them or claiming to buy tickets from them for any reason then you're either a corporate shill or terminally clueless.
