Recently I have seen adverts on Facebook about famous people who are reported to have died. All these turn out to be untrue. Apparently it is called "clickbait" designed to make you click the link, no doubt to then try to download something nasty to your computer. I have "shared" news items in all good faith only to find out later that they are not factually correct. In this age of "post-truth" news, one has to be very careful. Do not take things at face value!
