Car stickers are never a good idea, ever. Not only do they look ridiculous, they give random strangers access to important information about you and your life situation. Do not volunteer personal Information.

And then there is the uniquely stupid prospect of a piracy car sticker. What in the fuck gave you the idea that is somehow a good addition to your car? The activity ranges from unsavory to straight up illegal depending on where you live, why would anyone advertise they are doing that irl?
