“This tendency to friend strangers was illustrated last fall when the inquisitive IT security firm Sophos created two accounts using made-up names (anagrams for “false identity” and “stolen identity,” in fact) and profile pictures of a duck and a pair of cats. Each account proceeded to friend 100 people at random. Ninety-five people friended one of the two accounts, and one even received eight friend invitations from total strangers.”
