Good thinking jason_derp. This has actually been a growing phenomenon for a very long time. Art is art because a particular artist created it. An almost identical piece by an unrecognised person isn't art. That's the entire basis for the art auction market - "a genuine Rembrandt!". It's just got easier to get on the bandwagon as "art" has become simpler to create without needing a high level of technical skill. It's interesting though that what used to be called criminal damage - painting over someone else's walls without permission - is also now art, and in some cases extremely "valuable" art. We have a culture that advocates protest and disruption, and a lot of modern art merely reflects that tendency.
