Yes, that one has caused quite a stir on the Ebay boards. But, since word got out then I think MW is working on something and the service use even made a program for it.
Lots of others are going to try it manually because it seems to increase sell through...you can sell something in 1 day instead of 7 and you get more exposure. The discussion on the banned tool over on the Ebay store board is pretty heated about it.
I see benefits but I also see drawbacks. Especially if sniping programs set the end date when we make a snipe (I always Snipe )
