sholto writes "An aggressive expansion strategy by LinkedIn has backfired spectacularly amid accusations of identity fraud. Users complained the social network sent unrequested invites from their accounts to contacts and complete strangers, often with embarrassing results. One man claimed LinkedIn sent an invite from his account to an ex-girlfriend he broke up with 12 years ago who had moved state, changed her surname and her email address. ... 'This ex-girlfriend's Linked in profile has exactly ONE contact, ME. My wife keeps getting messages asking 'would you like to link to (her)? You have 1 contact in common!,' wrote Michael Caputo, a literary agent from Massachussetts."
