Europe
Honestly I don't get why this is so surprising, humans have been drawing graffiti for thousands of years. There's plenty of Ancient Roman graffiti to attest to that.
While yes, we should discourage it where possible, we also need to acknowledge that it's just as big a part of human nature, and culture, as the colosseum itself.
Graffiti is not acceptable in a modern world. There is a cost to cleaning that crap up. If you want to be recorded in history write a book.
I don't know if I can fit a whole book on the side of a building. Maybe if I write really small? 🤔
Completely true. Where would we be without Greek graffiti saying, “I visited the pyramids and they were mid”?
Just keeping up tradition. The ancient Romans also graffitied the colosseum.
