The UK’s advertising watchdog has spanked online operator William Hill and Betway for contravening gambling ad guidelines.

The Advertising Standards Authority (ASA) received a complaint regarding three promos issued via Hills’ @WillHillBet Twitter account. One promo featured a child jumping in the air holding a golf club and ball, with the accompanying text “#TheMasters has started! #yippee”.

The two other ads were promoting prop wagers on the gender of the latest royal baby and featured images of two teddy bears wearing crowns riding around on the back of a truck. The accompanying text read “Seen our teddy bears around London today?” while offering a free bet on the Grand National to anyone who took a photo of the bears and tweeted it.

The complainant felt the ads were “likely to be of particular appeal to children” and the ASA determined that the ads violated the rules prohibiting the use of children or young people in gambling marketing. Hills copped to the fact that the images weren’t acceptable and said it had taken steps to ensure there would be no repeat performance.
