Artists have told the BBC how their artwork is being stolen from social media and sold for profit online.
They claim malicious individuals are finding their art, often with the aid of an automated system known as a bot, and uploading it on to a website where it can be sold on a T-shirt without the artist's permission.
The individuals then comment underneath the artist's work on social media with a link to the T-shirt website, tricking the artist's fans into thinking it is an official product.
