Out of interest Des, have you ever had to refuse/ban/tell someone off for pretending not to be a pro and playing?
APAT has always been a really good natured community focussed type of tour, so I presume you don't worry too much about that.
It's largely self policed, but once or twice we've had questions asked about certain players and had a friendly discussion with them. On the two or three examples that this has happened the players have always had a good justification for playing. That would have been true in S1 also when the payout structure was very top heavy and a player would have had to win an event to have paid for their weekend.
