everyone revises their auctions from time to time, but some sellers are apparently even using a program that auto-revises every 11 minutes!
if you want to have a look at the problem, go to the art category, especially contempo american and make sure it's set to Newly Listed (which is the default). Look on the first page that comes up, click on any auction that has a bid & see what day it was actually listed. The few times I've checked 2-3 painters are always at the top of that page, everyone else paying $20 for FP is on page2-3 or ever further back almost instantly after they list. It does impact non-FP per it would still push you further back in the regular listings under newly listed if someone is constantly revising.
the good news is that the petition got picked up by auctionbytes:

other boards are talking about the problem and I understand the raw artist has web site about it. Hopefully something will be done. Please sign the petition (link at top of this thread) if you haven't already.
