Golfweek doesn't charge all of it's raters, yet. After I resigned from Golfweek's panel, I received a note from it's administration which served as a bill for annual "dues" of $250. With it was an explanation that they have traditionally grandfathered in older raters who didn't knowingly sign up for the dues program, unlike newer raters who have been charged $250 every year from inception. Not every GW rater has gotten a bill yet, but I believe they are working their way backwards through the roster. And yes, the $250 is in addition to "mandatory" rater camps/retreats/golf trips which GW raters are supposed to attend every other year.
So instead of endless speculation, that's the deal.
