A suggestion: One should consider the potential consequences of leaving their user ID on a forum when they also leave the user ID of someone they are slamming. There are some people that relish getting others upset, and would enjoy telling this seller what has appeared about them on this forum. eBay feedback is one thing; what has happen here has taken it to a higher level (although AS might get a new member). If the seller was nasty because of the feedback, what would be their response if they knew about this? You can see it happen on eBay's forum. It's not fun. Also, I wonder how much the Andale Counter on this auction has gone up since the above links were posted.
The seller could also leave a "follow-up" on the feedback they left the buyer. Not likely, but they could.
On a visit to England, Gandhi was asked, "What do you think of Western Civilization?" He thought for a moment and replied, "That would be a good idea."
