The Paranoid:
VKontakte offers me a friend of a person with whom we only called on mobile phones and called only by name. Mobile phones are not modern smart touchers and not even smart at all. Not even modern. And 5 years ago over the phrase "VKontakte - a branch of the FSB" almost everyone was friendly.
VTentakle and other social networks usually use an algorithm of the type of "o;, Vasya is familiar with Petey, and Pasha is familiar with Petey, let us offer Vasya to make friends with Pasha". And you’ve already set up conspiracy theories and you’re stockpiling a mortar.
