Personally, I would like to say thank you to the sellers who flout the Ebay rules and leave a positive rating (unfortunately the only way to do it) with a negative comment about non paying buyrers. I have the blocks in place as well and received this yesterday :

"can you please excempt me to be allowed to bid as ebay is restricting me i will pay asap if i win tnx" So I had a look at her feedback.

4/9/12 No payment or contact

21/9/12 No response or payment

6/10/12 Negative! Did not pay

I have had so many non-payers recently, why doesn't Ebay let you re-list an item for free when this happens?? My patience is wearing thin 😞
