public editing. But with more than 16 million articles to keep an eye on, it isn't easy. So, while Wikipedia benefits from being constantly updated with information from all over the world, it's also open to "vandals"（恣意破坏公共财物者）.

　　　Some of the damage is easy to notice. One person drew devil horns and a moustache on Microsoft chairman Bill Gate's photo, while another edited Greek philosopher Plato's biography to say he was a "Hawaiian weather man who is widely believed to have been a student of 'Barney the purple Dinosaur'.

　　　But other things are harder to spot. The most common form of vandalism (恣意破坏公共财物罪)involves adding tiny items of false information into the biography of a famous person. Unbelievably, some of this misinformation has appeared in newspapers, with The Daily Mail, The Guardian and The Independent all having fallen victim to the dirty tricks. For example, in an article about British comedian Sir Norman Wisdom, one newspaper claimed that he co-wrote Dame Vera Lynn's wartime hit There'll be bluebirds over the White Cliffs of Dover. He did no such thing. And in other article, it was reported that TV Theme tune composer Ronnie Hazlehurst had written the S Club 7's hit Reach again, not true. So, if you're going to use any information from Wikipedia, make sure you double-check it first.
