Every year, journalist Ben Black publishes a playful fake story on his community news site Cwmbran Life for April Fools’ Day.

Since 2018 the 48-year-old has spun yarns including a Hollywood-style sign on a mountain to a nudist cold-water swimming club at a lake.

In 2020, Mr Black published a fake story claiming Cwmbran had been recognised by Guinness World Records for having the most roundabouts per square kilometre.

Despite altering the wording of his article that afternoon, when he searched for it on 1 April he said he was “shocked” and “worried” to find the false information being used by Google’s AI tool and presented as real information.
