Does this look like collusion to you?

I found another one:

This seller has at least two shill accounts. Is this how you become a top-rated seller? I noticed that the seller has one neutral feedback. I looked at that auction and almost felt like I should tell the buyer that she paid more than she should have because there was shilling bidding. But I am trying to mind my own business.
Anyway, if shilling is this prevalent, I don't have a lot of faith in bidding on auctions anymore.

I've been watching this seller, lheseltine for months.

She has at least 3 shilling IDs although one of them seems to be taking a break:

As you mentioned, this is one of them: Member Id: 0***i

And another: Member Id: o***b
