In January, a former cop turned Facebook Inc. investigator posted an all-staff memo on the company’s internal message board. It began “Happy 2021 to everyone!!” and then proceeded to detail a new set of what he called “learnings.” The biggest one: A Mexican drug cartel was using Facebook to recruit, train and pay hit men.
The behavior was shocking and in clear violation of Facebook’s rules. But the company didn’t stop the cartel from posting on Facebook or Instagram, the company’s photo-sharing site.
