Hmmmmm! If one day this kind of device do arrive you would be more careful what you do. So that you will get rating of 5 star instead getting half a star. Other than user comment will hurt more than anything. But if this kind of device do come to reality it is quite useful for girls so that choosing a right guy would not be that hard anymore.
