Ebay recently announced that it will make major changes in the way that it handles feedback.  It will become impossible for sellers to leave negative or neutral feedback about buyers. Sellers that meet a list of positive criteria (fair shipping prices, accurate descriptions) will get lower listing rates, but many sellers believe they are getting socked with higher commission rates.

This is similar to what has happened with pay-per-click ads. A couple of years ago, Google announced a "quality score" for AdWords that penalized certain business models that it disliked. Google sharply hiked the prices on some types of websites, so things like e-books, shopping comparison sites, and lead-generation squeeze pages all became difficult to affordably advertise with pay-per-click.

For eBay's own sake, it's probably a good idea to try and improve the sense of security on the site. There have been a lot of abuses of the eBay system with outrageous shipping charges, misrepresented products and fraudulent buyers – so people are increasingly wary.

It's probably a bad idea for sellers and entrepreneurs to be completely dependent on one company's score or assessment of your business practices. Ebay is still a good way to sell products online, but it might be wise to consider diversifying your marketplace. You are always better off with your own website and alternate ways to drive traffic (aside from search engines and eBay listings), rather than depend heavily on just one company's policies and approval.

You don't want to put all your business eggs into someone else's basket!
