I agree with you except on one point. Sam is exactly the kind of person I thought was taking the money and I think most people probably suspected the same thing. I thought it was someone sitting around watching the twitter feed stealing money 150$ at a go. Someone who looked at this, possibly silly probably naive, social project and said 'This is stupid and I'm gonna show them how stupid it is.' I also knew that this person would eventually write a blog post about how smart they were for figuring out how to steal from people giving away money and how the project wasn't just foolish it was immoral.
