What were the listings for, did you get an email saying the reason for the takedown was fake? Were the items reinstated?
I did get an email, and yes it was saying they were counterfeit (one was a vintage burberry shirt, which has an S at the end) and I havent had any response from the email link etsy provides.
Did the email include contact details from Burberry?
There are counterfeit items out there (a LOT) and your item may have been one.
There are many, many, many counterfeits on Etsy and the company is trying to control them with bots. You may have been swept up in this effort.
Sewing pattern sellers are very reluctant to post designer patterns because we have been struggling with take downs as well.
