长难句

Stoked by fears that the data may have been used to try to influence elections in the US and Europe, and the discovery that Facebook collects a lot more data than the average person realises (including web browsing history and, in some cases, text messages), some users have started a #DeleteFacebook movement, including the co-founder of the Facebook-owned WhatsApp.

难句分析

本句的主干成分为：

some users have started a #DeleteFacebook movement。前面较长的部分是过去分词作原因状语，该状语的主干成分为stoked by fears and the discovery，且fears和the discovery后面都是由that引导的同位语从句，具体解释说明“担忧”和“发现”的内容，括号中的内容为插入语，补充说明数据的具体内容，最后的including the co-founder……是同位语成分。

参考译文

由于担心数据可能被用来影响美国和欧洲的选举，且发现Facebook收集的数据比普通人意识到的还要多很多（包括网页浏览历史，在某些情况下，还包括短信），一些用户发起了#DeleteFacebook（卸载Facebook）运动，其中包括Facebook旗下WhatsApp公司的联合创始人。
