Apparently they are testing a new system on the .com site whereby if you have a Dispatch Time rating of 4 or below, a red warning message is put on your Auction pages warning potential buyers that the "Seller has a low rating for shipping time".
Bear in mind that a star rating of 4 is considered 'Good' when you leave feedback.
This is just getting too ridiculous. :-(
