The Imitation Game and Pirates of the Caribbean star tried to join the netizens, but it only took her a few seconds to realize that social wasn’t for her and to know that she’d never come back. Keira Knightley was startled to see that just a few moments after opening her account, she already had hundreds of followers. She believes that backing out was a wise decision, because she wants to keep her children’s privacy intact until they are old enough to make their own decisions regarding whether or not they want to share their private lives with others.
