I don't have a linkedin acct. So imagine my shock when I "googled" myself and found a linkedin profile connecting my name to a company I presently have a consulting arrangement with (1099 not W2). I went ballistic and fired off an email to the consulting firm to take down the profile immediately or face legal action (a bluff). Couple days later, the company forwarded an email they received from linkedin confirming the profile had been taken down.

So this is just a heads up that even if you don't have a linkedin account, they will create one on your behalf so might better check (assuming you neither have nor want one).
