On eBay

I'm a bit worried about Ebay's changes in its non paying bidder program. Where is the certainty of knowing the buyer will be out of there in three NPBs? What if the buyer instead can terrorize the sellers, and by extension, the other buyers. A seller's time should be used listing more bargains and attending to paying customers, not people who think that they are too good to pay. I think sellers should be protected more, because when all the decent sellers are chased off eBay, the good buyers will have no where to turn.
Remember the rule of thumb, people. If you would be embarrassed, kicked out, or banned from a retail shop for doing what you are doing, don't do it online.
