I mean, my spouse has received death threats because of her line of work. We have 2 small children and we make sure they have no online presence at all (no pictures, comments, tags, etc), and we intentionally make sure to not have anything identifiable like this on our car. Our other family members have been included in threats before. If someone, for any reason, is targeting you, youre actually giving them a ton of information. Its easier to just not put it on your car and not risk it
