> The obvious risk with that approach is that if people do not realize that this applies only to the pirated version, you're risking bad reviews, which can cost you actual sales (you don't win anything just by keeping people from pirating your software, you only win if someone who is willing to buy but prefers to pirate chooses to buy instead).

Any time I've seen game devs try it the comments under those people were "you fix it by buying the game pirate".

And platforms like Steam allow you to review only bought games anyway
