The most frightening thing I’ve read as the administrator of one joke (now a long-comed) group is the message that "Fedor Vasilyev, a member of 827 groups, wants to join you".
Fedor is alone in 827 groups. There is nothing to read, no one to talk to, no one to argue. The circle of his interests is too wide for the ugly information ghetto in which Fedor is forced to dwell.
He walks in his ghostly blue polo and wants more friends.
