某网站是一家提供网络商品拍卖的电子商务公司。小丽在该网站“好美化妆品”卖家发现，其出售的某化妆品比她在商店里购买的同一品牌的商品便宜4成。在仔细核对了网上商品介绍及相关图片后，小丽按既定购物流程购买了该化妆品。随后，小丽发现网上购得的化妆品属于假货。在与卖家协商退货不成又无法获知卖家详细联系方式的情况下，小丽将该网站告上了法庭。要求法院根据消费者权益保护的相关规定，维护其合法权益，判决该网站赔偿损失。但是，法院并没有采纳小丽的诉求。因为，“好美化妆品”是根据该网站的服务协议开设的网店，该网站仅提供买卖双方的交易平台，并在网页上提示，并不保证卖家所卖商品的真伪。在小丽寻找卖家时，该网站也尽其所能地提供了卖家注册时的联系方式。
根据案例分析回答以下问题：
(1)从案例引发的事实，思考网络服务商的责任规范应有哪些基本要求
(2)在什么样的情况下，该网站可能要承担法律责任
