The UK’s advertising watchdog has told bookmakers to stop robbing the cradle, even when the youth they’re allegedly exploiting is 22 years old.

On Wednesday, the UK’s Advertising Standards Authority (ASA) upheld complaints filed against gambling operators Bet365, Coral Interactive and Betfred’s Totesport brand. All three complaints were in relation to social media posts the bookies made this summer featuring images of golfer Jordan Spieth.

The Committee of Advertising Practice (CAP) code prohibits gambling operators from employing images of anyone who looks a little too close to ‘barely legal’ territory, on the grounds that such images could have extra appeal for younger viewers and thus lead them into gambling perdition.

Specifically, the code frowns on images of anyone who is either under the age of 25 years or who appears to be under 25 from playing “a significant role” in marketing communications, unless the image in question appears in a forum where the viewer can directly place a wager, for example, on the operator’s own website. Even then, the person in the image must be the direct subject of the bet in question and cannot be shown in a gambling context.
