People who move on often become aware when they train in a verifiable school. A while back, on e-budo, one young man was very pissed off when he found he had been training at a school claiming a certain style of aikido. when he went out west and train in another school he was pissed he had wasted 2 years. Can't say as I would blame him. He thought he was doing an aikikai style and went to a legit aikikai school and they basically laughed at him.
