We're a small cat shelter that accepts donations using a Paypal donate button on our website. In the past few months, we've had fairly frequent small amounts "donated", and then charged back as unauthorized. Since the amounts are not standard donation amounts (which are usually $5, $10, $50, $100, etc), and the listed customer is not a regular donor or in our records at all, I'm assuming that they are at least mainly stolen card numbers, and someone is "testing" the card number.
It's frustrating enough that these all sync to Quickbooks and we have to deal with the clutter of a payment and then a reversal, but it's really annoying that we are losing the amount of the Paypal fee for these. There doesn't seem to be a way to dispute these chargebacks and getting Paypal to refund the fees to us. Any suggestions, beyond discontinuing accepting donations this way?
