Who made a suspicious amount of bids for the same seller.

A buyer bid on an item that I watched a few minutes ago on a popular auction website. That person made 515 bids in the past 30 days -- with 21 percent of their bids linked to that same seller!

The item that I'm interested in purchasing is a stamp set that was never in high demand, and is located in Russia.

I've been a member on that website for over a decade, and I've never seen another user place anywhere near 108 bids for the same seller.

It's either that buyer is really interested in that sellers items -- or they're a shill bidder trying to capitalize on the situation.

Needless to say, I've decided to not bid on items from that seller...
