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?
It's not a good idea to put any sort of identity on your car since people don't generally think nice things about the drivers they see on the road with them. One of my friends refuses to put a Jesus fish bumper sticker in case she cuts someone off or something and they get mad at God.
I had one on the back of my car that was a T-Rex biting a chunk out of the ichthys symbol. Lasted a lot longer than I thought it would living in the Bible Belt before someone ripped it off. People will definitely take your car decorations personally.
Putting any sticker on your car is a great way to give free information out to people about yourself. Don’t give out free information to people about yourself.
Maybe if it's just a jolly roger with "*ARRR" under it. Those in the know will understand, for others it's just a silly pop culture reference. And has plausible deniability ("What? I just really like Pirates of the Caribbean and Sea of Thieves!").
Yeah this is my thought as well. I see nothing wrong with mostly surface level info for bumper stickers. However, I wouldn't advertise doing anything against the law or hell, even less popular stuff then most. It unfortunately can single you out for potential vehicle damage or worse.
Wow, people here really hate bumper stickers. I think of them as a fun little bit of self expression that reminds me there are other humans in the road. I really don't think the risk of getting your car keyed because of one is nearly as high as it's being made out to be, and police using a bumper sticker as any sort of evidence seems pretty unlikely too. Do whatever you're comfortable with of course, but I wouldn't be too worried.
Depending on where I'm the world you are, there is nothing that can be done. I at least know where I live in the US, I could put a sticker for something like l337x or Ru Tracker and the worst thing that could happen (without any links) is that someone keys off the stickers.
Though I feel like I'd be more likely to be pressured by a police officer to remove the stickers for some bullshit made-up law that those stickers are in fact illegal (despite it only being a logo/name of the website).
Also, just having a sticker might attract attention, but the people whose attention it tracks would need actual proof of anything wrong going on before they actually make a move.
