A Brazilian Army intelligence officer reportedly used Tinder to infiltrate and effect the arrests of nearly two dozen activists in São Paulo, according to Motherboard.

Army Captain Willian Pina Botelho is said to have created numerous undercover accounts on social media networks, including Tinder, where he told women he was trying to connect with “leftist” activists. A woman he met on Tinder eventually led him to a group planning a demonstration against Interim President Michel Temer in São Paulo.

Oh oh.
