ebay pays for quality clicks. Not just for clicks in general. They describe quality clicks as people who bid on something. Even if they lose the auction, they still push the auction price up and they consider that a quality click for that reason.
Besides all that, eBay just made changes again to the overall payment structure. I don't know what's happening now, but my eBay earnings dried up this month, so I decided to pull most of my eBay capsules since I make much more money from Amazon. Besides, eBay has always been known to play around with major complex changes that become confusing.
