Interesting that this thread has come up because I am just beginning the pain with a buyer in Portugal. He paid on Friday, I shipped on Monday (from UK, by Airmail) and tonight, I get a Paypal notification that this has gone to dispute for non delivery.
The buyers ebay account is no longer active and all the activity was in the last month. I suspect a scammer, but have to rely on Paypal's dispute process now.
Is it right/fair to share ebay user IDs for those with which we have had problems?
