When did eBay scrap the rule forbidding a blocked bidder from using a different ID?

Thanks for the answers guys but the policy now makes no reference to blocked bidders, only unwelcome bidders and eBay is defining that not the seller. It was explicitly stated that eBay would act against those who used other IDs to bid on a seller's items when that seller had put a bidder on their blocked bidder list. That is now not stated anywhere. I have mail from Ebay CS confirming that one serial non-payer, blocked by me under three different IDs has not broken any ebay rules or policies! They reassure me that I can still block a member but make it clear in the same sentence that I cannot block a member, only a member's ID. To make this into a really stupid idea, a seller cannot know the true identity of a bidder until the sale ends and order details are readable. We do not have the option of setting "not on my blocked bidder list under another ID" on of buyer requirements.
