That doesn't stop Ebay from trying. It seems every week they come out with some new initiative to try to enforce consistency between the thousands of sellers on the site. All these initiatives really do is create busywork and resentment for the sellers.
My wife has been selling new Women's clothes on Ebay for many years, and has seen this all first-hand. Her life these days is nothing but stress, as she has to go through and change thousands of listings for the latest boondoggle. Her income has been decreasing steadily over the years and it's almost too much to bear now.
If Ebay keeps trying to be Amazon, they are doomed to fail.
