Facebook believes between 3 and 4 per cent of its more than 2 billion monthly active users were fake accounts.
Facebook’s vice president of product management, Guy Rosen, said more work needed to be done to improve such detection tools.
“In addition, in many areas – whether it’s spam, porn or fake accounts – we’re up against sophisticated adversaries who continually change tactics to circumvent our controls, which means we must continuously build and adapt our efforts.
“It’s why we’re investing heavily in more people and better technology to make Facebook safer for everyone.”
