Not exactly... here is the scoop.
The dude (lets call him Tim, cuz that is his name) was working for Big Sky as an ambassador (not working for the YC). There was no banging of a celebrity.
He was in line for first tram, and one of the instructors took a "big money" client to get on the first tram. This is something that the ski school has not done in a very long time, as its dickish. (This was not a "first tracks" lesson). So Tim tried to talk the instructor out of being a dick, but wasn't super polite about it. He sort of trash talked him on the way up, and the instructor reported it. Tim's friend got blamed for it, and banned, so Tim admitted to it, so as to spare his friend from being banned. Tim showed up to board and his pass didn't work, so he went up via Explorer, then Challenger, then onto the tram.
He then dropped into the little couloir, and ended up crashing with a spectacular tomahawk down most of the little. He definitely got down part of it though, and the dude shreds.
Since he had to cut through the north summit snow field on Moonlight Property, he was banned from both resorts, and also received tickets for theft of service, and trespassing.
