I'm  seeing more and more auctions where it is clear that the use of "schill bidders" is becoming very common place for many sellers.  "Schill bidders"  are bidders who bid on behalf of the seller, with the intent of increasing the final selling price, with no intention of ever purchasing the item they are bidding on. 

This is relatively easy to spot.  First look for sellers who are offering items way below normal value,  with low opening bids and no reserves.  Just watcg what happens and especially the names of the bidders.  You will find the same names in numerous auctions selling similar items yet these bidders seem to stop bidding when the item begins to reach fair and reasonable amounts.
