Hey, I'm a developer from China. I was looking for assets to buy on one of our local shopping sites and happened to come across your work. I noticed that the listing there is just someone reselling your stuff. I figured you should know, because I really hate it when people take someone else's hard work and sell it for cheap. I tried DMing you on X, but you don't follow me, so I couldn't get through. If you want, you can reach me on X: @ly1609988. I can send you the URL. That shopping platform has a complaint/report channel where you can prove you're the original creator, force them to take the listing down, and maybe even claim compensation. I'm happy to help you with it.
Also, I just want to say I really admire your beautiful work. Thanks!
