i wouldn't go as far as to say the op commited fraud....but he did definitely game the system....
my cousin & i share the same middle & last name....we also have the same first initial....
a couple of years ago he needed to stay at a particular hilton property but it was sold out....since he had no status with hilton, he asked me to make the reservation for him using the diamond gaurantee....
long story short, he paid rack rate to get the room & i got the points & stay credit....
