the3coopers IMO the group of  "experienced sellers" you appear to refer to is an extremely small group that are not really representative of the wider range of ebay sellers nor are they most successful ebay sellers around.

IMO I don't think that there is a REAL issue that relates to snipers opening not as described claims for description revisions that are purely made to increase traffic...

BUT ... if someone did leave feedback such as in your example comment, there are grounds for ebay to remove anyway - as sellers can not change descriptions after bids have been made -only add to them.
