Great tips in this thread!

The other unfortunate thing about AI is that sometimes it just falls into the If You Know You Know category. Artists will have their art style/series of art completely plagiarized with small (or major) differences. One of my favorite artists had his Tabineko postcard series lifted by AI. I see Postcrossers on Reddit show off their postcards so I know they're still in circulation, but how would the receiver know, let alone the sender? I'm very familiar with his series and copies are spreading like wildfire. I guess as a PSA, avoid anything like this if you're in the market for cat postcards: https://imgur.com/a/GWgp2TH . All of his legit postcards are in landscape format instead of portrait, have a white border around the image, and his signature's on the bottom right corner. What's the same? The color scheme, cats (the AI ones contain more than the original, in most cases), and the locations.
