It's the site that Mat mentioned. There's a certain amount of history between this site and theirs that I can't really comment on (because I don't know all that much) but they don't like golfwrx.
You can't mention golfwrx on their site. The profanity filter removes it and any posts alluding to it quickly get deleted. Compare that with here where you can. Also, BSG are a business and are in the business of selling golf equipment whereas here, there are no ulterior motives for hyping a particular club or shaft.
There's some other things too but I'm sure that you can find them out for yourself
