The company ran a campaign on Monday aimed at promoting its new Arsenal shirt, which generated personalized images of the new product bearing the Twitter usernames of people who liked a promotional tweet.
That prompted Adidas’ UK account to send out images of the shirt bearing abusive phrases including the n-word as well as references to the Holocaust.
Others made light of the Hillsborough disaster, in which 96 football fans were fatally crushed inside a stadium in 1989, and the disappearance of Madeleine McCann, a British child who went missing in Portugal in 2007.
An Adidas spokesperson told CNN: “As part of our partnership launch with Arsenal we have been made aware of the abuse of a Twitter personalization mechanic created to allow excited fans to get their name on the back of the new jersey.
“Due to a small minority creating offensive versions of this we have immediately turned off the functionality and the Twitter team will be investigating.”
The incident also raises questions about why Twitter users were able to create racist and anti-Semitic handles, some of which appeared to use subtle misspellings in order to avoid detection.
CNN has approached Twitter for comment.
The botched campaign follows similar efforts by other companies which were also hijacked by online trolls.
A Twitter campaign run by the New England Patriots in 2014 led to offensive names being branded on the back of the NFL team’s jersey.
And British snack food company Walkers apologized in 2017 after its Twitter account sent out auto-generated pictures of its ambassador, ex-footballer Gary Lineker, holding aloft images of serial killer Harold Shipman and Jimmy Savile, a television host who was accused of sexual assault following his death in 2011.
