I have been looking through a bidder's profile, and they have all green positive feedback on ebay, but there are a couple of bad feedbacks as buyers, but the odd thing is that they are marked with green like a positive feedback instead of red. Why is this? I also looked at their ebay page, and they have a note about making sure that items are described as they are or they will open a return case. Are they a serial refunder? It is really hard to tell, since the vast majority of their feedback is positive, in fact it is 100% green, even though there were a couple of bad ones that were marked green as well.
