I have a gacha re-sell store and I could point out at least three store that are selling copybotted gacha items. Yes, it's POSSIBLE that I'm wrong, but I'd be willing to bet my store on it. Anyone that pays any attention to the gacha market could pick them out after a while. (Spotting copybotted gacha items is far easier.) I have contacted a few of the creators and they seem universally uninterested in the copybotting. All of them told me some variation of, "It's too big a hassle to have it taken down and, even if I did, they would just open a new store and do it again."
This is an issue that will never be resolved because the only people that could resolve it, the content creators, don't seem too interested in it. About the only thing that most of us could do would be to buy one of the items and then leave a review saying that it's ripped, copybotted, whatever.
