Oh, I just hate this. I am very anti-grafitti to begin with. People who use their time and resources to make the world uglier for everyone else are kind of shitty in my book. Now folks have a tool to do large scale uglification at low risk to themselves. You can argue six-story advertisements are a blight on society, and I would agree with this. But spray painted advertisements are even worse, and I don't think vandalism is a good way to fight against this assault on our attention. I doubt that few graffiti vandals have such lofty goals in mind anyways. Drones with cameras can also now easily float outside of windows, high up apartment buildings, and spy on people in places where they have a reasonable expectation of privacy. The world is changing in mostly good ways, but I see a lot of potential for drones making the world a worse place in which to live.
I hate 'vandalism', which is what this is explicitly called, but enjoy graffiti in some situations. As tng says, when wielded correctly it's essentially street art. The difference might seem subjective but I think it mostly comes down to common sense. I've seen a lot of dull buildings in Austin beautified by guys with spray cans.
Based on my experience with you Mike, my guess is that you enjoy some #streetart. How do you distinguish between what is art and what is graffiti?
If I like it, it's art. God, doesn't that sound egocentric? But that was one my great realizations years ago, when I would go to art museums and wonder what was good art and what wasn't. It was incredibly liberating to realize that if I liked it, it was art. That makes all of us art critics! I think flagamuffin said it fairly well with regards to street art. Some of the #streetart links we've seen here are fabulous. They add something beautiful. Tagging your initials on street signs adds something negative. Yes, it can be very subjective, and some things are deep into the gray zone, but that drone vandalism is just vandalism.
