"Wow. You must be some kind of amazing jerk. You've actually succeeded in getting yourself banned from a list purely devoted to setting up rides to Burning Man events. How hard can it be to grasp the concept of what would be appropriate on such a list? Apparently too hard for you. Give serious thought to having yourself institutionalized, because I find it hard to believe that your IQ could be any higher than the current temperature at the South Pole.

That, of course, would be somewhere below zero. You'll be excited to learn that I've written to your ISP with the recommendation that your account be terminated with extreme prejudice. Been a thrill, gonna miss you. B'bye."
