Did CMS actually cut pay based on online forum talk?

I've heard stories that rads was specifically targeted for pay cuts based on posts from auntminnie/sdn...this can't possibly be true can it? Don't they have access to every radiologists tax returns/ billing information to calculate actual average compensation? Using anecdotal unverifiable income reported on an anonymous forum feels like the most ridiculous reason for pay cuts I can think of...
