Five of the worst social media stuff-ups Donald Trump should perhaps think twice before commenting on Twitter. Picture: Ap Source: AP SOCIAL media is still in its infancy. In relative terms that baby is still learning to walk, which means there's going to be a lot of attempts that end in tears. And thanks to mobile phones, these wobbly moments can be captured and broadcast on the internet with the speed of a viral YouTube video of a toddler falling over. The more offensive the stuff-up, the more public it will be. News.com.au has put together a list of some of the biggest social media stuff ups of the last few years. Donald Trump. The fact Trump even has a Twitter account could be seen in some circles as a mistake. Trump has the nasty habit of using national tragedies as an opportunity for self promotion. Take for example this tweet about the Boston bomber, Dzhokhar Tsarnev: Was that really necessary, Donald? Even sadder, the tweet was retweeted 5,981 times and favourites 2788 times. The tweet came just hours after Trump tweeted that the Tsaernaev brothers had help from "other cell members," a theory that was completely unverified at the time of posting and one that was proved completely false as time wore on. Fred Nile Between his views on asylum seekers and gays and lesbians, it's easy to get distracted from the truly persecuted: Straight white families. According to unsubstantiated claims Nile said same sex couples earn 29 per cent more than couples with different genders. "Only a family-friendly economy will stop inequality," he tweeted. Oh Fred. Woody Harrelson If you are going to participate in a Q &A on Reddit (known as an 'AMA' - 'Ask Me Anything'), it's essential to be prepared to answer any question. It seems as though actor Woody Harrelson didn't really know what he was in for when he agreed to participate in an AMA to promote his film, Rampart. Woody Harrelson in a scene from film The Messenger. The AMA was pretty short lived. He refused to answer personal questions and eventually fled the site. It all began after a Reddit user asked him if he remembers sleeping with a high school girl in the '80s and subsequently never called her back. "You didn't call her afterwards," the user wrote. She cried a lot. Do you remember any of this and can confirm, or have you been so knee deep in Hollywood pooty for so long that this qualifies as a mere blip? Harrelson denied the story and said "I don't want to answer questions about that." "Let's focus on the film, people," he wrote. Yeah ... Reddit kind of doesn't work that way. Harrelson barely answered any other questions and eventually fled his own AMA, leaving Reddit users to mock him collectively, flooding the site with unflattering memes, GIFs and images of the actor. Applebees Here's some advice for all businesses with a social media presence: Try to keep the social media stuff-ups to a minimum by not creating a second social media stuff up! Picture: Applebee's.com Source: Supplied In January the US fast food chain fired one of its waitresses after she posted an image of the receipt she received from a pastor on Facebook. The receipt gave an excuse for failing to tip: "I give God 10%," she wrote. "why do you get 18." Naturally, social media users did not take kindly to this and many hours were spent criticising the company online. But instead of keeping its mouth shut, Applebee's responded to the comments left on its Facebook page with a series of long winded statements. Then it was caught hiding or deleting negative user comments and picking fights with users, and denied both allegations when the proof was right there on its page. One of the latest comments on the page read "I for one am enjoying Applebee's PR suicide." Touche. Susan Boyle Rule one of inventing a promotional Twitter hashtag: make sure you get an objective opinion to prevent any accidental faux pas. British singer Susan Boyle performs on the stage during the 60th Italian Music Festival at the Ariston Theatre in Sanremo 16/02/2010. Sadly for Susan Boyle, her social media representatives didn't think there was anything wrong with asking people to use the hashtag "#Susanalbumparty" when tweeting about her album launch. The hashtag went viral for all the wrong reasons when fans notice it could be read as "Su's anal bum party."
