On last week's episode of TLDR, we spoke to OkCupid President and founder Christian Rudder about the company's recent disclosure that it had been running an ethically questionable experiment on its users

In the experiment, the company took users who the site's algorithm found were bad matches (based on a battery of questions users answer) and told them they were actually good matches, and vice versa. In the interview I took issue with this experiment for a number of reasons. One of those reasons is because buried in the list of questions users get on OkCupid is this question: "Do you feel there are any circumstances in which a person is obligated to have sex with you?" I argued that this could lead to unsafe dating situations, to which Rudder replied "I mean there's also a lot of stuff we don't ask, I mean, y'know, so like, we don't know any of our users. Y'know so like we make no claim to the safety for anyone, and obviously we do everything we can to encourage a safe environment. But like, I think it's disingenuous to suggest that we're setting up people in dangerous situations." 

One enterprising hacker named Meitar Moscovitz (AKA Maymay) has developed a plugin to try and detect potentially dangerous situations before they occur.

Maymay's tool, called "Predator Alert for OkCupid," performs a couple of functions. First, it scours a profile's answers to see if they've given an answer that is, as Maymay puts it, "concerning." It also attempts to use facial recognition to scan user profile pictures against the United States Sex Offender Registry.
