This is where problems can come about. For example, in the past I have sold custom built computers on ebay. I actually had a couple of people once try to blackmail me out of money or extra parts after the computer arrived. One case in specific was where I shipped out a Athlon 64 3200+ computer with a modded Radeon 9700 Pro that had a heat pipe cooler installed. The guy claimed the cooler came completely off during shipping, but he didn't notice, powered up and fried the card,and blamed me and wanted me to refund him around $100.00 back or he would leave a negative. Thing is though, 1. the heat pipe block was bolted on, it wouldn't have come loose. 2. When asked for pics, he couldn't provide any to show me this damage. 3. The computer case had a large side window. It would have been impossible to miss something like this as the cooler was quite large. 4. The cooler would have made alot of noise as the case was being taken out of the box.
I had a couple other cases like this, which is why I stopped leaving feedback first when a buyer paid. I also had something like this happen when I first started selling on ebay, when some guy got a bulk lot of laserdisc from me, stated after it arrived he was unhappy with the lot, but would be happy if I gave him for free others I had up for sale. When asked for pics to prove there was issues with the items, the guy folded and gave up. There is plenty of bad bidders out there that are more then willing to pay, because once they do and the item is shipped, they have their foot in the door to pull scams, blackmail, and paypal fraud. Just ask Nectarsis about that one. Due to the ability taken away on the sellers part to leave truthful feedback, the possibility for scams like this has risen. Sure you can still leave a detailed feedback, it just wont reflect on the persons rating the way it should. Simply means anymore sellers will have to be more careful and actually read the bidders feedback statements, not the numbers.
