Had newbie (from Ferntree Gully, Vic) buy from me, plus bought about 20-30 items from other sellers, no payment no contact and no response. Contacted other sellers to see if they were paid, nope. So of the 10 sellers I contacted none received payment, we all opened UIDs, yet this buyer has not been made NARU.  So they are free to go and bid, win and not pay on as many auctions as they like! System is a joke, regardless of whether you have blocks in place, the buyer should be booted off!
