I agree with GreenBean. However, some of this depends on what you sell and the class of buyer. If you sell electronics, there is a proclivity of some buyers to go in with the attitude that many items are not genuine.
I sold an LG phone that had a serial number that could be traced on the LG website. A buyer jumped to the conclusion that the item was not authentic, because the battery was dead. His quote was that he had never seen a dead battery in a cell phone, so by default, the item was not real.
My point is that it only takes one buyer now to mess up your account. So, we all need to have a back-up plan. Unfortunately, no matter how careful we are, certain buyers will file disputes. With the dispute process now in eBay's hands and not Paypal, the chance of linking accounts is greater than before.
