EBay Caution

[Harford20]

I have recently noted concern for shilling on a Ebay seller by the name of "e-fu" with (2191 stars). I have now bid on this T206 Frank Chance card twice, as it has been set back up for auction recently (having ? not sold the first time). I started to look at "e-fu" completed auctions and over 12 different auctions have an under 10-min bidder "new" bidder with 0-5 stars. Searching his completed auctions, this is seen is various different eras of cards--from T206, W515, T202, and even 1959 Topps football. All have had final minute bids by either "i***a" (24 stars), "e***u" (6 stars) or "b***8" (0 stars).

I have received contact from the seller regarding card condition initially, but no contact regarding reselling of card recently.

Now either someone has a hugely variable collection just starting to purchase from eBay, or this seller is shilling.

Has anyone ever contacted eBay regarding shilling, and can you offer ideas on how to start this investigation? Has contact with eBay been effective?

Thanks
