An anonymous reader writes: Facebook has today taken out full-page ads in U.K. newspapers ahead of the general election that's scheduled to take place next month. These ads are designed to educate the public about how to spot fake news online. Appearing in nationwide publications, including the Guardian and the Telegraph, Facebook's "Tips for spotting false news" ad is similar to the one it published in France last month and covers such areas as being skeptical of misleading headlines, spotting manipulated images, and checking the URL of the story. The advice offered may not always help, however -- under "Consider the photos," for example, the text reads: "You can search for the photo or image to verify where it came from." But anyone requiring advice on how to spot fake news through a newspaper ad likely isn't tech savvy enough to know how to do that or to even understand what it means. Alongside these ads, Facebook also revealed that is has deleted "tens of thousands" of accounts that it believes were deliberately spreading fake news and that it is also updating its algorithms to demote articles it suspects of carrying dubious messaging.
