Any individual persons webcam is going to be boring as fuck most of the time but if you had access to a bunch of them and selected the right footage there ' s tons of scenarios of how you could use that against them . Are you aware of what a fucking big job this would be ? There ' s no way to automate this task , there ' s no computer program capable of recognizing people doing shady shit . You would literally have to spend every day sorting through ten thousands of hours , maybe more , of footage of people looking like manonthecomputer . jpg all day , in order to occasionally find one guy you can potentially extort per day , likely going some days without even finding anything extortable . Then you would have to actually contact the mark in some way and negotiate your way to some money . And like you said , only a certain , small percentage are actually going to pay . In short , after all this work , you might be able to extort some guy for money ever 100 th day . And considering how the worst you ' re likely to caugh someone doing is masturbating or smoking weed , that person probably doesn ' t care enough to pay luxurious amounts of money . In the end , your project has gained you the most boring day job imaginable and you ' re getting paid less than minimum wage without the income even being reliable . Trying to justify hacking web cameras by saying that you could totally earn lots of money by doing so is like trying to justify the act of constantly spending all your money on lottery tickets because you can imagine the possibilty of earning millions that way .
