Check the seller’s feedback history and use “Posh Authenticate” service

Return Fraud: To get their money back, the buyer has to submit a claim that follows the rules of the Poshmark protection program, so the most common false claim is that the item arrived in damaged condition. Scammers target sellers of high-end merchandise. The fraudster will make a purchase, then send back a counterfeit copy of the item, claiming that the seller sent them a fake. POSH AUTHENTICATE service will verify the authenticity of designer goods. Sellers should avoid leaving high account balances sitting there for too long. Account takeover attacks are always within the realm of possibility, and active seller accounts on Poshmark could be very high-value targets. Only fraudsters will insist on completing transactions offsite. Once you leave the Poshmark platform, you are no longer under their purchase protection coverage. Beware of messages asking you to send information to other websites or emails. Scammers will frequently try to establish off-site communications and transactions, where they can’t be tracked or held accountable. Please share & like. I hope this helps someone.
