The UK’s advertising regulator has banned two promotions for “fan tokens” from Arsenal Football Club, saying they were misleading supporters over the risks of investing in cryptocurrencies.

Arsenal said it would seek an independent review of the ruling “to seek greater clarity on the ASA’s current position”.

The Arsenal ad ban was one of a number published by the regulator on Wednesday, including bans on advertisements by BT, the cider brand Kopparberg, and the online retailer THG.

An increasing number of football clubs are becoming involved with cryptoassets, including Watford through shirt sponsorships from cryptocurrency trading platforms and Barcelona and Juventus which offered their own “fan tokens” or non-fungible tokens (NFTs) that serve as digital memorabilia – while proving potentially very lucrative for the clubs.

However, some have faced issues given the lack of regulation of the space. Manchester City last month suspended a partnership with a cryptocurrency startup that appeared to have a minimal corporate presence.

The head of the Arsenal Supporters Trust, Tim Payton, last month told the Times newspaper that football clubs should have a “greater duty-of-care responsibility toward their fans” and suggested there should be more regulation of cryptocurrencies.

An Arsenal spokesperson said: “We take our responsibilities with regard to marketing to our fans very seriously. We carefully considered the communications to fans regarding our promotions and provided information regarding financial risks.”

The latest ASA rulings – 25 in total – also included a ban on another crypto advert. Skrill, described as an “online wallet and money transfer service”, took advantage of consumers’ inexperience, the regulator said.

BT was rapped for an advert for broadband internet which claimed to guarantee speeds of 60MB/s, after a complaint. THG, the online retailer of consumer products like makeup and protein shakes, made “misleading claims over potential discounts for hair products” on its Lookfantastic website.

The regulator said that a Kopparberg radio ad broke rules because it implied that alcohol could contribute to an individual’s popularityand featured people who appeared to be under the age of 25.

The ASA also named and shamed four influencers who published ads on their Instagram feeds, including for not properly disclosing they were paid for the posts – a growing problem for the regulator. They were reality TV personalities Charlotte Dawson and Chloe Ferry, the beauty blogger Jamie Genevieve and video blogger Anastasia Kingsnorth.

It was the second time that Ferry has been censured within six months, after she was criticised in June for posting an ad for a company that claimed it could help customers write off up to 85% of their debts.

In Marc,h the ASA warned it would crack down on influencers who broke the rules. Under the UK advertising code, paid-for endorsements must be clearly marked, typically using a hashtag such as #ad or #spon, short for advertising or sponsored.

Complaints against two adverts – by the clothing retailer Jigsaw and construction machinery retailer JMAC – were upheld for objectifying women.

Regulators also upheld 26 complaints that a Halloween billboard poster for Blackpool Pleasure Beach was “inappropriate and disturbing for young children” – although Norfolk Dinosaur Park avoided censure for its poster following complaints that it was too scary.
