I have no idea what they do in regard to slop, but my opinion of Etsy is pretty terrible at this point.
I did just go look to see if I could find a current policy. My 2026 noai.DuckDuckGo results have a bunch of complaints by slop sellers complaining that their listings have been removed without warning or providing explanations of how to keep selling while adhering to Etsy policy.
So I guess they’re doing something, though it sounds like a whack-a-mole problem.
If you’ve been buying paper patterns from stores, it’s worth looking to see if the designers you like have their own websites. A lot of them sell patterns directly or will link to where they can be bought.
