But this guy has an ivy league education in computer science and business. He should know exactly how much information he gives away online and where it goes. I’m guessing he just didn’t really care much about being caught in the first place. If I was him I would have gone into it expecting to be caught eventually. Getting away with it would be nice but not the expected outcome. If you’re expecting to get caught anyways you aren’t going to put terribly much effort into completely covering all your tracks.
