Facebook has apologised after it approved an ad campaign targeted at people interested in a conspiracy theory favoured by white nationalists.
News site the Intercept was able to launch a promotion aimed at 168,000 users interested in “white genocide.”
Prosecutors believe the conspiracy theory, which claims “outside forces” want to exterminate the white race, may have motivated the man who attacked a Pittsburgh synagogue last week.
A senior UK MP has criticised Facebook for approving the ad campaign.
In a tweet, Damian Collins, the chair of the Digital, Culture, Media and Sport Committee, called Facebook’s approval of the ad campaign “appalling and irresponsible”.
