Shopify has taken down a site advertised by rapper Ye, formerly known as Kanye West, that sold swastika t-shirts.

The rapper ran an advertisement on Sunday during the Super Bowl that directed viewers to visit Yeezy.com, where it promoted a single product — a $20 t-shirt with a black swastika. The site was online until Tuesday morning.

A Shopify spokesperson from the Canadian e-commerce company said the site violated the rules of its platform.

“This merchant did not engage in authentic commerce practices and violated our terms so we removed them from Shopify,” the spokesperson said in a statement.
