Websites that harbour disruptive, shocking or malicious adverts will appear less frequently on users news feeds, Facebook has said.Facebook于日前回应，用户新的的消息流中“破坏性的、骇人听闻的、蓄意的”网站广告数将不会有所增加。The social network is tweaking the algorithm that picks posts for feeds to do a better job of spotting low quality web pages.

Facebook said its analysis of hundreds of thousands of web pages helped it to identify those run by spammers.Facebook认为，他们对成千上万网页的分析，不会协助他们辨识这些由垃圾邮件发送者运营的网站。The updated algorithm would be rolled out across its many territories over the next few months.接下来的几个月，升级的算法将相继指定各个运营区。
