Why would the legality make this test invalid or unfair? Illegal things still happen. I have seen countless street signs with graffiti on them. I could see rebellious teenagers doing this on purpose without fully understanding or caring about the consequences. Search google images for 'street sign graffiti' and you will see thousands of examples.

There has been an outbreak of modified stop signs near me. Some are quite professionally done with stickers championing pet projects. Stop animal farming, stop eating meat etc. If they weren’t at the end of a street, they would definitely look like a marketing campaign (which I suppose is exactly what they are).
