I can't see how this can be happening. Freehub bodies are splined, with the matching splines stamped out of the sprockets. Only cases of spinning sprockets I've seen is when someone has tried to run loose sprockets on an aluminium body, where it's possible for the steel sprocket to shear a path through the aluminium splines.
And torqueing down hard enough to get a sprocket w/o the spline engagement to stay put while riding seems equally improbable.
