In relation to recent scam transactions I have experienced, it was suggested that I track all items but not upload the tracking to Ebay. I was advised that this would prevent a lot of scammers as they first try an Item Not Recieved case. Having tracking that can be uploaded to the INR case means the case would be closed in my favour. It was further said that once a case has been closed in a sellers favour, a second case could not be opened.

I would like to know if this is correct information and if used by others, does it help?
