That name brought back memories.

Ever since he left I became the long hair music dude around here.

NFT art is hot atm though, you make mad cash off of it, it's kind that he wants to share the profit with you but as it's your art you should probably have the final saying about whether you want someone to else to become the owner.

I think if it's a gig that netted you less than 100usd to begin with, you're better off cutting your losses and chalking it up to a learning experience. You'll find plenty of artists saying that even though someone commissioned your services, you still own the product post-transaction, or that you get to choose whatever Creative Commons your work is under after you've already sold it, but I've yet to find a legal system that agrees.

Really the only surefire legal protection you have without putting it under the proper CC and having them sign some Activision-style End User License Agreement is from someone claiming they made the art themselves. There's a CC for Attribution, but most legal systems have laws that precede CC when it comes to fraudulent claims of manufacture origin. But even then, you're talking about an exhaustive process that will cost you more time than even the upsold piece is worth, and you're not going to get damages for it.

Your options in the future boil down to making people agree in writing that they don't actually own the thing they bought from you. It's your labor, sell it on whatever terms you want, but don't be surprised if clients say that that doesn't sound like a fair deal to them.

To add on to what others have said in this thread, he may be selling it but who's buying? He may not end up making any profit off it at all.

Deleted, a couple years ago. Still wonder why that was, used to seem like a genuine dude...

Maybe this really is just for attention; for stirring something in regard to the Grounds again; a little way of exacting vengeance without really being vengeful about it somehow... maybe he's flat out broke and desperate for new revenue, who knows...

Seems the legal possibilities have pretty much all been detailed. Does seem like you probably have the right to request a takedown if you want to, or request a split on payments if you'd see it as a potential extra revenue stream, or as you say just ignore this whole shizzle, wonder if it'd really sell at all, and what kind of rep he'd get for it long-term...

Sad to see he's resorting to stuff like this though. :/

If you really want to do this btw I've got some archives. :) Just lemme know.
