Monitored or not, My point remains that there are better things to do for an employee of Marriott corporate or the hotel to do with their time.

Do you honestly think someone made a business decision to pay an employee to troll forums, looking for 1 in a 100 threads where people have talked about earning too many points, to then try to decipher from a user name who that customer was....and then take the points back? If you do, I have a bridge to sell you.
