BTW to the person upset about their priv items now being sold publically and asked if it's scammy the official faq says this:
Q. I said I would only sell 20 copies of an item, but it ended up being really popular. Can I sell more? A. No. Many sellers will sell limited CWs for more money, and people buy them for their potentially higher value. Because of this, if you publicly stated an item would only have a max number of copies (or batches) and attempt to change it later, this is considered scamming and will result in an official warning for such.
Q. What if I said an item is permanently retired but I start to sell it again? A. This is considered scamming the same as selling more than the max number of stated copies (previously batches) and will result in an official warning for scamming.
I think if the person in question publically confirmed that there would only be less than ten copies ever and/or it was perma retired, you might have a case? either way I'd def ask the artist for a trade back first. Since it's been a few years they might have forgotten they ever traded w you
