Then the title should say replica, not just have the brand name Tripp in it. If eBay is OK with this then they are allowing unscrupulous sellers to trick buyers into thinking their products are something they're not.

Would they allow a seller to advertise a "replica" handbag with Prada or Gucci in the title ?  Or replica sunglasses with Ray Ban in the title if they weren't Ray Ban? I don't see how this is any different.
