davidcyclebackAs far as "family and roomates" go-- beyond other investigative information, I suspect eBay is going strictly by matching addresses registered with eBay and/or PayPal.
From a practical standpoint, if eBay were to explicitly allow family or others with the same address and paid employee's at one's work address to bid, eBay might as well simply forget about policing shilling. eBay doesn't have a case by case Vulcan Mind Probe to judge the mind set of the wife who share's the seller's bed at night.
