Lots of people would have no problem registering the game to "Sir Pantsy Higginbothom <pantsy@throwaway-email-provider.com>" and then what good does their little name screen do?
If they always reset your registration count no questions asked, there is no point in even having that there.
It seems like they're trying to strike a balance but I just don't see the point. There's still extra hassle involved here, interestingly much of it is on the publisher himself, and there's no particular benefit for anyone. The publisher gains nothing from these measures because they are so easy to circumvent and they'll just creep out / bother users that registered the copy in their real name. Users gain nothing from these measures because they are almost not there and there's some slight intrusion made after buying 10 games. They don't add anything to the experience, unless you like your name flashing up as one of the intro credits.
So there's really no point to any of this. They should just rip it out and then they could put shiny "DRM-free" buttons all over.
