Don't do it.

The top copied product at the moment is the beats headphones due to their large popularity.

You can bet your life that they have hundreds of laywers targetting online sellers of them and will report any copies they see on ebay.

Ebay may not remove some sellers straight away but they will eventually.

DO NOT use others existings listings as a gauge to know whether a product is allowed or not on ebay. I have made this mistake myself and it has burnt me.

Some items do not get reported but do eventually after a while. It is a risk on your ebay account if you try it.
