As far as I’m aware pin position information is freely communicable without penalty. Why anyone would want to know a club when the distance information is readily available and the wind very changeable I don’t know.
You’d be surprised what information some have been found to be sharing. If it’s windy, how many extra clubs they took on such and such hole, and so on. We were having all sorts of issues with it especially, dare I say it, with younger members.
So the club banned their use except in emergencies. Even that caused problems, with a minority trying to use a very liberal interpretation of what amounts to an emergency!
Seriously, you couldn’t make this stuff up.
