Replying to Proposition of an NS game of sorts...

So I was driving around and saw a car with an NS sticker on it. I was thinking about it and thought, what if an NSer signed a sticker with his/her user name (just keep one in your wallet or whatever) and put that shit on the car of said NS sticker already applied. Every time you see a car with an NS sticker on it, tag the car with your ski or NS sticker with your name on it... YAY or NAY on a shitty or sweet idea?
