“It’s not for me. I’d be opening myself up too much. I don’t want to sound like a complete innocent – I’ve looked at things, of course. But it’s such spewing. If I look at it, I’ll be affected. It’s like dancing with the devil,” Aniston told the New York Times.

Bradley Cooper

The “American Sniper” star took the most retweeted selfie of all time, but he’s still one of the celebrities who avoid social media. He’s staying away from it because he wants his fans to focus on his acting, without details about his personal like that would get in the way.

Scarlett Johansson

Scarlett Johansson Avoids Social Media

Staying away from social media is also the norm for Scarlett Johansson. “I can’t think of anything I’d rather do less than have to continuously share details of my everyday life. I’m always surprised that certain actors have Twitter accounts. I guess they use it in a way that works for them. But I’d rather that people had less access to my personal life. If I could keep it that way, I’d be a happy lady,” she told Interview magazine.

Many celebrities who avoid social media have serious reasons for it, but the “Sherlock” star claims that he just couldn’t edit himself in tweet form. “Tweeting is about being pithy.

Daniel Radcliffe
