It's all about me. It's putting me in the frame. I'm getting attention and when I post that to social media, I'm getting the confirmation that I need from other people that I'm awesome, you don't care about the tourist attraction you're destroying; you don't care about annoying people in your social media feed ... you're not even thinking about the consequences of your actions, so who cares if you're dangling off the side of the Eiffel Tower?
