You have no sales, you also have no protection as reselling is not allowed on Etsy, which makes you an easy target for scammers
Yes, this is a SCAM!
Yes, you have been targeted by scammers. You have no sales. And what you are selling is not handmade by you, you are reselling, which is not allowed. https://www.etsy.com/legal/policy/reselling/239324376512
Definitely a scam so please be careful as they like to target new sellers
Read the Etsy handbook for what can be sold here. Reselling is not allowed
If they are threatening to close down your shop, then it sounds like a scam!
Also, what are you selling? Did you handmade those items?
