The digital bread crumbs you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like.
主干：The crumbs make it easy to reconstruce...
you leave everywhere 是定语从句，省略了关系代词that，修饰crumbs; make it easy for...to do...结构中，it 是形式宾语，真正的宾语是不定式 to reconstruct...。easy是宾语补语，for引导出不定式的逻辑主语strangers。句末who, where和what引导的三个名词性从句都是reconstruct的宾语。
译文：你处处留下的数字面包碎屑很容易让陌生人推想出你是谁，你在哪里，你对什么感兴趣。
