Absolutely agree with the law of the land and the example in your post written by Rebecca (FAA) clearly defines this.
However for a thread to manifest itself into this proportion presumes that this side of the pond is a grey area in its interpretation albeit with conflicting local practices.
Flying in the US for "Cheap" turbine time (last I heard) is also discouraged by the CAA (Google:- Rip off Britain), and have heard stories of pilots having a disclusion on PIC hours, so will happily write off my couple of minutes either side.
Cheers.
JimL's post clarifies the rotors turning issue though and time where Pilots duties are being conducted should be logged in my opinion...
