The blasted UK tabloids do this all the time. Many of them are owned by the same media group which also own smaller, regional/town newspaper/websites too. So the same article keeps coming up, slightly rewritten headline or a couple of paragraphs changed etc in each sister website.

The worst part is there is no actual TSA announcement to be found, only advice from random 'experts' and speculations. All this is done to drive traffic to show more ads. So depending on the website, you have to go outside and check if they say the sky is blue (a usual joke about Daily Mail over here)
