Reporting a Problem eBay Listing
eBay can't possibly monitor millions of items for sale on a daily basis, picking out the problem children from all the items for sale. eBay relies on eBay members to let it know when a shady listing is afoot. If you ever smell something fishy, for goodness' sake, report it to eBay. Sometimes eBay takes a few days to cancel a listing, but rest assured that eBay invests a lot of time protecting its users from fraudulent sellers.
If you see something that just doesn't look right, you should report the listing via an online form that is accessed when you click the Report Item link at the right, just above the Item specifics in the description area of the item.
eBay doesn't personally prosecute its users. However, eBay does have a stake in protecting its honest users — and will act as an intermediary between honest eBay users and law-enforcement agencies.
