Numerous unauthorized transactions

[resale_hk]

Hello,

Recently I have received so many unauthorized purchases from various buyers. After printing the shipping label and dropping off with the courier, I receive a message stating that the transaction was not authorized.

This is very frustrating because there are multiple cases open on PayPal and eBay doesn't allow you cancel transactions without open a case.

Does anyone have suggestions on how to avoid this or spot these scammers?

Thanks.

are you losing your sales money? PayPal has a "seller protection" policy.

I would add these buyers to your block list

Well sine eBay refuses to allow negative feedback for buyers the sellers are left to their own vices to try to identify and block the scammers. As others have stated adding them to your blocked buyers list is a first step however after awhile they simply drop their old eBay account/ID and get a new one and continue the scamming. You may want to file an FBI internet crime complaint and hopefully the FBI will notice trends or identify particular individuals that have a consistent pattern. Link to the FBI ICC site is

Unauthorized transaction disputes should be closed in your favor if you can prove that you shipped to the same shipping address the buyer used at checkout.

Are you providing that proof to eBay/PayPal?
