An eBay spokesman said the website had blocked sales of the item and added that it will continue to remove items "listed maliciously", according to the International Business Times.
Although critics including singer The Weeknd described themselves as "shocked" and "offended" by the adverts, the boy's mother Terry Mango said she thought the "furore" was overblown.
"Am the mum and this is one of hundreds of outfits my son has modelled... Stop crying Wolf all the time, unnecessary issue here... Get over it," wrote Terry Mango in a social media post which has now been deleted.
She later went on ITV's This Morning to say she hadn't expected the media storm but added: "I think everybody should respect different opinions based on racism."
The Evening Standard has contacted eBay for further comment.
