From public urination to falling asleep at the wheel: The most complained about ads of 2021 so far Source: Unsplash/Jonas Leupe. Ad Standards has released its list of the most-complained about ads in 2021 so far, with an ad depicting a man urinating causing the most offence by many lengths. Issues around discrimination and vilification drove a number of the complaints, while health and safety concerns and unsafe driving also got people riled up. The most complained about ad by a long shot was a Crazy Domains ad that featured a man urinating on a building. This attracted some 283 complaints, compared to the second-most complained about ad — one showing people using a hose to varying degrees of success, and including the words ‘bloody’ and ‘freaking’ — which received 74.
