The politically divisive Facebook ads bought during the 2016 campaign by the Russia-connected “troll farm” known as the Internet Research Agency were purchased through the social media network’s self-service ad manager platform.

These ads focused on topics like LGBT issues, immigration and gun rights, according to Facebook’s chief security officer Alex Stamos, and sources told CNN at least one referenced Black Lives Matter and targeted audiences in Ferguson, Missouri and Baltimore.

This is how easy it is today to buy ads on the platform and target specific groups of people.
