I have bottomless hatred for LinkedIn because, a few years ago, I allowed them to access my contacts. They claimed they'd use them only to find which were on LinkedIn. Instead, they emailed <i>all of my contacts</i> using <i>my name</i> to invite them to join LinkedIn.<p>At the time, this included old girlfriends, old bosses, and lots of other incredibly awkward contacts.<p>I believe they were eventually the subjects of a class-action lawsuit over this. What utter, disgusting sleazebags.
