I agree that exposing these shills over and over is helpful to the people who might not have read the past exposes. At least no one on N54 who reads one of these threads can get ripped off by Probstein or PWCC but claim that they did not know. It may be dull to hear what is effectively the same story again, but the solution is not to read it. The titles are clear enough.
As for eBay, don't hold your breath: its management actively encourages shilling. Used to be a piece of cake to figure out who was shilling; just cross-reference the shilling account with the seller's account. That is how Broadway Rick got nailed:

eBay tackled the challenge posed by shill bidders
by hiding the identities of the underbidders. It greatly reduced the number of complaints about shilling not because the activity ceased but because no one could prove it any longer.
