Sifting over all these posts, IMO Sean makes the best points of which the top one is...
In the end, the course has ALL of the power. If they don't wish to be rated, then don't allow it. It ends there. There is no arm wrangling, coercion, or forcing them to do anything. Its a simple as "No thank you, have a nice day!""
Actually you will have to be more specific. Clubs do of course have complete control over their own guest policy. But, as far as I know, clubs are not allowed by the magazines to opt out from being listed at all. And, so, some may choose to deal with raters entirely because they're afraid they will be rated poorly if they don't.
Tom,
I think Sean gave a reasonable answer, but to me I see it like this:
The vast majority of the courses on top 100 are privates, of which I can't imagine any one of them are hurting for more members/income. So as best as I can tell, its just plain old massive ego if any of these courses want to be on the list much less rise to the top.
As for publics like Bandon and Cabot, its simple really. When they show up, if they show their rater card, a simple "we're glad to have you here today, will that be cash or Credit Card?" is all thats needed. If they throw a tantrum about not being comp'd, let them throw em it...they'll pony up, especially if they made all the effort to get to a remote location. Its no different that dealing with a 2 year old...you don't give em the candy right?
P.S. If the vast majority of raters are in fact good guys as has been claimed and of which I believe to be true based on a few I know, then their ratings should overcome a few spoiled kids...
