I was checking out this listing that was posted in the GAT, and noticed that the highest bidder who also bid right when it was listed has 100% bidding activity with the seller.
Normally I don’t report something that “might” be a shill, but this one I worry a bit more than usual as these are high end items. It would be unfortunate if someone were to unjustly pay an extra $1,000 because of a shill. Anyway, if you want to report it feel free.
