Many of new sellers in caricature category are using images from popular and high rated users work. I don’t Know that how could they got approval for publish this. I seen that my work is also using by someone for selling his gig…!!
If someone is using your images, then try to write him asking to immediately remove them. Give them 1 or 2 days maybe, then if nothing happens write Customer Support and provide all the evidences you have… then wait for the problem to be solved
