This article is hysterically funny. True, Facebook is spyware plain and simple, they track all your interactions, including browser history and searches, in order to serve targeted advertising for the benefit of their paid advertisers. To think that Russia would create fake FB accounts to get info on Macron's team or supporters is totally absurd, what possible political value could that info have? 

A more likely theory is the Macron team did it themselves to determine which of their team is stupid enough to add FB "friends" to whom they had no real life connections.
