Watch what you put in your titles of your listings.

EBay will remove any items with "not" etc, ie, Adidas trainers, not Gucci, Prada.
They also remove any items with "like" etc, ie, Adidas trainers, like puma.

This is because it is against ebay regulations and allows your item to appear in more categorys and searches than it is suppose to be in, ie if your item is adidas it shouldnt be listed under Prada etc.

Hope this guide helps.
