I have another non-paying bidder on eBay. She started with 0 feedback, so I was worried in the first place. She didn't respond to messages or the invoice and then all of a sudden she had a feedback, so I checked it out and sure enough, it's a false positive. Another seller left feedback saying she doesn't respond to messages and that she hasn't paid. So, block tempersgirl before she bids and then doesn't follow through with her commitment.
