Creators of fake accounts and news pages on Facebook are learning from their past mistakes and making themselves harder to track and identify, posing new challenges in preventing the platform from being used for political misinformation, cyber security experts say.

This was apparent as Facebook tried to determine who created pages it said were aimed at sowing dissension among US voters ahead of congressional elections in November. The company said it had removed 32 fake pages and accounts from Facebook and Instagram involved in what it called “coordinated inauthentic behavior.”
