The first author of this also developed tools that allow you to analyse all sorts of personality traits (including sexual orientation) via FB likes. He was aware and publicised of the potential consequences and risks here, but I seem to remember thinking his reasons for publishing were justified at the time. As he was part of the psychology department during his PhD, I think his papers will have been extensively scrutinised by ethics boards and the like. Mini disclaimer: I vaguely knew him from university and didn't get on with him. However, I don't think he was the type of person to put people at risk for personal glory.
