Clay Shirky sez, "While googling around for instructions on deleting my Facebook profile, I discovered a form of digital graffiti which is one part last-ditch strategy to three parts _cri de coeur_: accounts renamed by frustrated LinkedIn users desperate to get off the service. I have no idea how common this is, but in just two searches, I came across a Mr. Delete This Account from the San Francisco area, who turns out to have company, as there are three other Mr. Delete This Account's on the service (San Diego; Enid, OK; and Liege, Belgium). There are also two users named Delete My Profile, four named Delete This Profile, and no fewer than ten named Unsubscribe Unsubscribe (the Humbert Humbert of the 21c.) There is also some unintentional hilarity on individual profile pages -- one of the Unsubscribe Unsubscribes is a Relationship Manager, while a user with the first name of 'delete delete delete' and the last name of 'delete delete delete' is a Hospitality Professional in Australia. LinkedIn is very solicitous about asking "Would you like to add delete delete delete delete delete delete to your network?" Um, no."
This was how I got rid of my LinkedIn account in the end, and why I never signed back up again.
