The operator has come under fire for posting sexually explicit content on one of its social media accounts.
The posts were made as part of the company’s own marketing initiative; however, fans were not pleased their club had made such links.
A number of supporters criticised the Canaries for striking a deal with BK8 after finding out the company had used adult content to promote itself.
A similar issue resulted in 1xBet being dropped by Premier League clubs Liverpool, Chelsea and Tottenham Hotspur in September 2019.
Following the reaction, Norwich made sure its new sponsor had removed the explicit content from its accounts and stressed it did not “align with the wider vision and values” of Norwich City.
A spokesman from the club said: “The club worked swiftly with BK8 to remove the posts following the announcement of the new partnership.”
They also added that the club will now be reviewing its due diligence process going forward.
BK8 issued its own response on the matter, where it was very apologetic to the club and its fans.
The company said: “BK8 would like to wholeheartedly apologise for any offence caused by our historical marketing.
“We accept this form of marketing isn’t befitting of a Premier League partnership. We have immediately removed all marketing material of this nature and will conduct a review of our marketing strategy moving forward.”
The Asian betting firm had previously replaced Dafabet to become Norwich City’s main shirt sponsor for the upcoming 2021-22 season.
