Recently I have noticed there are multiple pages on facebook advertisements where myshopify links are involved. These merchants from shopify are creating fake sites and collecting money through online payment by selling electronics,jackets at attractive rates. Within two days they delete their site and create new one. I think shopify has to focus on this fraud and prevent it as soon as possible.
I second this, got scammed by an online archery dealer on Facebook. Supposed to be in Oklahoma, text I received thanking me for my payment had a Los Angeles pre fix. You should verify these vendors, I will never purchase again from a Shopify store/vendor.
