DeviantArt premium subscribers have received notifications that their work is available in NFT format – a way to trade originals of any digital culture by adding a unique crypto-tag to them. This is how the Nyan Cat GIF and the work of 3D artist Beeple (Mike Winkelmann - Beeple Crap) were sold. The price tags for such works can reach tens of millions of dollars. Not surprisingly, scammers are trying to capitalize on the popularity of such trading.
Artist Ismail Inceoglu discovered that his work was not only for sale in the OpenSea (a popular NFT-trading platform) but had already been sold there – and he didn't know about it. The authors of the project assured that the new lots have been removed and the accounts have been blocked, but the problem of already sold exhibits is being discussed with obvious reluctance like any marketplace would do.
Formally, they do not have an obligation to check the lot, they are only a middleware between the seller and the buyer, and on the site itself, there are many buttons for filing a complaint. However, the story can undermine the credibility of NFT auctions. DeviantArt, on the other hand, has received very positive feedback for the new feature.
