It isn't that hard to imagine. Say that you're an executive entering into highly sensitive negotiations with Apple. The Apple executives that you're dealing with are now in your email contacts list. Eagle-eyed Google spots them and sends them an invitation in your name to join you on Google+. The Apple executives are less than thrilled to see you mentioning Google, much less endorsing it. At your next meeting, things are awkward, and you're not sure why.
How about this possibility? You've applied for an IT job at Dunkin' Donuts headquarters. Because you entered into an obscure agreement during a Starbucks promotion, that company is able to send out a tweet in your name extolling its coffee. Now, why haven't you heard back from Dunkin' Donuts? you wonder. The interview seemed to go great.
Or let's say that the social site's automated email software has a glitch — it could happen, right? Because of the glitch, not one message goes out to everyone on your list, but 1,000. You're suddenly shunned as a spammer.

Do what you must to make sure that every message with your name on it is actually from you.
