Fakes don't hang around very long when the orange belts are over in the corner arguing about who gets to take the brown belt first when its sparring night. And it they do, they will learn.
TwinFist said:warn him that if he spars wearing it, that your browns will fight him at brown belt level.
This covers my thoughts on the initial question, and the secondary question that he might be some kind of faker. I've never met a video trained student, but I imagine that s/he would stick out like a sore thumb.
