The dangers of tweeting something you shouldn't were highlighted last week when a woman was fired from her new job before she'd even started.
This tweet from Justine Sacco in 2013 still haunts her to this day.
Sacco tweeted "Going to Africa. Hope I don't get AIDS. Just kidding. I'm white!" before she boarded a flight, not aware of what would follow once she stepped off the plane.
Even though she deleted the tweet, it was way too late.
Sacco lost her PR job, was receiving death threats and had to hide herself away from the public firestorm.
The hashtag #HasJustineLandedYet was trending worldwide during her 11 hour flight from London to Cape Town. Although Justine only had 173 followers on Twitter, her tweet was soon noticed by writer Sam Biddle and retweeted to his 15,000 followers.
"How did @JustineSacco get a PR job?!" a Twitter user wrote.
"In light of @JustineSacco disgusting racist tweet, I’m donating to @care today" another wrote.
"All I want for Christmas is to see @JustineSacco’s face when her plane lands and she checks her inbox/voicemail."
The tweets kept on coming.
"Oh man, @JustineSacco is going to have the most painful phone-turning-on moment ever when her plane lands. We are about to watch this @JustineSacco b**ch get fired. In REAL time. Before she even KNOWS she’s getting fired."
The company that she worked for, IAC (who own OKCupid and Vimeo) released a statement, all while Justine was still on her flight.
"This is an outrageous, offensive comment. Employee in question currently unreachable on an into flight," they wrote.
Once she landed, she was greeted with missed calls, and hundreds of notifications from her social media pages. She apologised, and flew home before her holiday was over. The damage was done.
"I cried out my body weight in the first 24 hours. You don’t sleep. You wake up in the middle of the night forgetting where you are," Sacco said.
Family members told her she'd damaged their name, and Buzzfeed already had an article up on their site - "16 Tweets Justine Sacco Regrets."
Sacco left London, and headed for New York. But she the ridicule continued. Sam Biddle, who originally retweeted her, publicly apologised to her.
It highlights how careful you need to be with social media. It's accessible to everyone, and it could cost you alot more than you'd ever expect.
Anyone can read your tweets, including your employer. Don’t say anything on twitter you wouldn’t say to their face.
Cella got a new job at a pizza shop, and then tweeted this.
