The Advertising Standards Authority (ASA) has warned the online gambling industry of the need to pay even more attention to advertising conduct amid the coronavirus (COVID-19) outbreak. The ASA stated that because the nationwide lockdown has created a ‘captive audience’ and heightened uncertainty and anxiousness, many individuals are more susceptible to the risks associated with gambling. It is anticipated that gambling may be used by some as a means of distraction from the pandemic. As such, the ASA has instructed gambling operators to ensure that they comply with their responsibilities under the UK Advertising Codes. Firm action will be taken against those who do not meet the required standards and, in their marketing, fail to consider the context of the crisis and how it may affect consumers’ behaviour and expectations.
