So I'm on tumblr and I see this CPA offer for Beats headphones popping up EVERYWHERE. The guy has obviously hacked accounts or is using a script of some kind that causes tumblr blogs to post his links. I talked to a few of the people whom it's happening to and they have no idea how it got posted through their account. I'm guessing I should go ahead and do some investigating, find out who it is and report them to their network? What would you do?
