Title: Facebook's live streaming(网络直播) is criticized after mosque(*) shooting(枪击).

　　live　adj.现场直播的，实况转播的

The speed at which a video of the New Zealand mosque shooting spread across social media platforms has demonstrated yet again(再次) that tech companies such as Facebook Inc. are still struggling(体现了内容管控的艰难) to control content, especially from popular services(业务，平台) that offer live streaming of events.

　　spread across　跨领域 / 平台传播

　　Inc　股份有限公司　　是 Incorporated 的缩写

 

While(起到对比作用) platforms including Twitter(推特) Inc. and YouTube said they moved fast(迅速) to scrub(删除) any content related to the incident from their sites, people(网民们，用户们) reported it was still widely available(随处可见) hours after(在什么之后的好几个小时内) being first uploaded to the alleged shooter's(疑是枪手嫌疑人) Facebook account.

Facebook Chief Executive Officer(CEO 首席执行官) Mark Zuckerberg has acknowledged the difficulty of policing content from the 2.7 billion users that power Facebook's wildly profitable advertising engine. The company's business model depends on showing people posts they're most apt to have an emotional reaction to, which often has the side effect of amplifying fake(假的) news and extremism.

　　take down　撤下，拆除　　to take down a tent　拆掉帐篷

　　

 

Facebook has 15,000 employees(公司雇员) and contractors sifting through posts to take down offensive content. Zuckerberg has said artificial intelligence(AI) algorithms(AI算法), which the company already uses to identify nudity and terrorist content, will eventually handle most of this sorting. But at the moment, even the most sophisticated AI software struggles in categories where context matters(重要).
