Does it really matter where your referrals come from on ebay's affiliate programme?

I recently signed up for ebay's partner network and during the signup process they asked me to enter the domain of the site I am going to advertise the products and the catgory of the products I want to market. If I decide that I just want to use a classified site to market the product and that I want to advertise a variation of products would ebay notice and close my account or is it possible to advertise a car when I said I would market a cell phone
