I don't really understand the string bid theory (not to be confused with string theory).

Is the theory that a sham string bidder is trying to drive the price up but then quit just before he becomes the high bidder?

Or that the sham string bidder will drive the price up until they actually become the high bidder, but hope someone else will then outbid their last incremental bid?

Or is it that they drive the price up and then retract their last winning bid?

Or maybe some combination of the three?

I always just thought string bidders were inexperienced with eBay and didn't know what they were doing.
