As announced on May 19, Mystery Auctions are being banned from eBay this month. I don’t really understand the appeal of Mystery Auctions, but I assume it is basically a gambling endeavor.
Some eBayers are really passionate about Mystery Auctions. I joined this group thinking that it had to do with Pulsers: http://groups.ebay.com/forum/Mystery-Pulse-List/Welcome/1500025753
Surprisingly, there were $126,934 in eBay sales of Mystery Auctions last month. 9,189 mystery items were sold.
