I’m sure I’m not the only one noticing quite a bit of art theft on fiverr, where sellers will take another artists art, upload it into their portfolio and try to sell it as their own.
Perhaps there could be an automated system when the seller uploads their portfolio images, and they are checked like a google reverse image search to see if they appear in other places online. If enough instances of that image are found, then the gig is flagged for human review to see if the art is actually stolen from a different artist, or if that seller has just uploaded their original art onto other places on the web, like their website or social media.
Something like that, anyway. Art theft is awful!
