No controls for scammers. I could not even find the reviews/feedback for sellers before you purchase. I do know to BE SURE to look for when the seller was last on line. Many shops abandoned and Poshmark does not delete within a reasonable time of inactivity. I almost purchased from a seller who had not been on line since April of 2016. Make sure you send a message and ask every question from the seller regarding an item before purchase. PAY THROUGH PAYPAL FOR PROTECTION WHEN POSHMARK IGNORES YOU. THEY WILL GET ACTION. I am sure there are honest sellers on the site. But have found most are not up front of honest about the listings even if you do get the product. BUYER BEWARE----BUYER BEWARE!
