Chargebacks cost us time and money to resolve. I've had to deal with $105 in chargebacks over the last 3 days. Please make sure that you are authorized to use the PayPal account from which you send donations. We do appreciate the donations, but chargebacks are a liability - not an asset.
Our procedure for dealing with chargebacks is as follows:
1st time: You will be removed from the donor group - regardless of how much was charged back and how much you have donated to date. We will also accept no further donations from the account.
2nd time: You will be permanently banned for abuse of the donation system.
Reminds me of that time someone chargedback'd on a $300 donation to SW. Had a feeling it was going to happen, mind you. Really though, who the heck charges back $5? Hope explanations were provided.
It was one single user that used three different PayPal accounts in donations. It occurred during September's initial donation flood so I didn't catch it. The offending user has been banned and refunds issued.
