Yes and no, IIRC the last time I installed a cracked game (disclaimer: it has been a decade) I was required to install the game first with internet OFF, then replace the .exe with a cracked version. But it’s entirely possible that there are a lot of newbies doing this without blocking traffic, and launching the game with their internet on and without the crack. So Unity might not see EVERY pirate, but they will definitely see SOME. How many, I’m not sure.
