I like to think (or hope) he was only being facetious and trying to score some free "vouch points".  I can't imagine what the HH online account security would think when someone's account suddenly gets loaded with tens of thousands of  points and has hardly ever stayed on a Hilton property or used a Hilton credit card.  LOL, the alarms would start ringing off the walls.  My guess is the account would be shut down VERY quickly.
