A few weeks back, I posted on here regarding an Etsy messaging scam where "buyers" were asking for personal email details in order to complete a purchase. Today, another has come to my attention - please beware of a message on the Etsy app from "Etsy"/"Etsy Support"/"Order Processing System" stating that your store is currently "unable to accept new orders" until you confirm your email address in the chat, so that you can apparently complete verification via a link. I would suggest to simply ignore these messages, do not respond and mark as spam.
Please remain vigilant - have a great day guys!
