I work at KSL, and I got that same e-mail this morning. Spam blocker flagged it, but I glanced at it anyway. Funny, but I made a variation of my name on one mailing list ten or twenty years ago, and I still get junk mail with it. My parents bought me a turntable from Allied Electronics in about 1967, and their initials got transcribed funny on the order....They still get mail with that name and address, even though they are both dead.

I've made a hobby of tracking snailmail mailing lists for years. I'm not so concerned about that, though it can be annoying. (Even worse when you track the sale to a government agency, but I digress.)
I'm pretty sure that KSL didn't sell or give away the list. I certainly never gave them permission to do that, as far as I know. Even if they had, I'm quite sure that they wouldn't have sold to a sleazy operation. That leads me to believe that there was a security breach at Bonneville. If I were them, I'd be scrambling to find out what other information might have been compromised. They might have even gotten into things like the payroll files. That could be a big problem.
