Same bidder across the store’s auctions

Checked in store reports. This pattern only appears across many of a store’s auctions, so a single listing can’t show it. Susbid checks it once enough people have checked a store’s auctions: look up a store.

What it looks like on eBay

• Across several of one seller’s auctions, the same masked name and feedback score keeps showing up in the bid history.
• Because eBay masks names, two different people can share a masked name. Matching the feedback score too makes a match likely, not certain.

Why it counts

A secondary account bidding on one seller’s items tends to show up across many of that seller’s auctions. Single auctions can’t show this; it only appears across many.

Innocent explanations

A present sign is a reason to look closer, not a conclusion. Common innocent reasons for this one:

• Loyal repeat customers bid on most of a store’s auctions.
• Masked names collide: a***e (5) can be several different people in a large category.

Check it yourself

1. Open the bid histories of several of the seller’s completed auctions.
2. Note the masked names and feedback scores that repeat.
