Let 'em dirty the walls
Urban landscape without it our cities would not be the same, vandalism is often not perceived as a form of "street art" Some people call certain plants "weed" but they are having a role in the ecosystem, naming can be destructive sometime and create misconceptions, its the same with "vendal tagging" you might see it as "weed" but to me they have also their space in our urban nature, cities without them is like a beautiful women without a dress.
