I heard they do put your name into their database but you can still get items thru. I think it is more like they pick random packages and if they grabbed yours and your name was in their database they open it up and go thru it better where as if they picked yours up at random and it didn't show up in the computer they might just say, too small and throw it back in the container.

I don't know exactly the method but it is still a numbers game.
