"The Ghost"

A few days ago I was in a Strip Casino and observed a guy walking around watching the table games. He was 6'4" to 6'5", 200 lbs., short brown hair and about 45 or so. It wasn't very much later and I was barred, along with a couple of other dudes. I was later informed by an associate that this guy was known as "The Ghost". Does anyone know this guy's real name and who he works for????? I would like to send him a message as he is cutting into my profits. It's not as though the casinos can't afford to loose a few dollars to me as they are taking so much from the non-advantage players.
