Mark Zuckerberg created a program called FaceMash while at Harvard that allowed users to vote on which of two female student photos was "hotter" without consent. This violated the ethics principle of disclosing potential dangers to users or the public from software, as the program posed harm to the girls by judging them based on looks without permission. Zuckerberg obtained the photos by hacking into college dorm directories and did not inform the girls, putting them in danger without disclosure. He created the misogynistic program after a breakup, rationalizing the violation as a right to potentially destroy other women's lives. The program went viral and crashed the Harvard network, resulting in Zuckerberg's probation.
