论文摘要
在线社交媒体通常代表了独特的信息来源，并且可以访问可靠和无偏见的内容至关重要，尤其是在危机和有争议的事件中。我们研究了俄罗斯 - 乌克兰冲突的前几个月在Facebook和Twitter上散发的宣传和错误信息的传播。通过利用两个大型社交媒体帖子的大型数据集，我们估计了两个平台上俄罗斯宣传和低质地内容的普遍性，描述了时间模式，并突出了超级普遍性在扩增不可靠内容中所扮演的不成比例的角色。我们推断出Facebook页面和Twitter用户共享宣传和错误信息的政治倾向，并观察到他们往往比平均水平更正确。通过估计两个平台主持的内容量，我们表明只有约8-15％的帖子和推文共享与俄罗斯宣传或不信任的来源的链接。总体而言，我们的发现表明，Facebook和Twitter仍然容易受到虐待，尤其是在危机期间：我们强调需要紧急解决此问题以保持在线对话的完整性。
Online social media represent an oftentimes unique source of information, and having access to reliable and unbiased content is crucial, especially during crises and contentious events. We study the spread of propaganda and misinformation that circulated on Facebook and Twitter during the first few months of the Russia-Ukraine conflict. By leveraging two large datasets of millions of social media posts, we estimate the prevalence of Russian propaganda and low-credibility content on the two platforms, describing temporal patterns and highlighting the disproportionate role played by superspreaders in amplifying unreliable content. We infer the political leaning of Facebook pages and Twitter users sharing propaganda and misinformation, and observe they tend to be more right-leaning than the average. By estimating the amount of content moderated by the two platforms, we show that only about 8-15% of the posts and tweets sharing links to Russian propaganda or untrustworthy sources were removed. Overall, our findings show that Facebook and Twitter are still vulnerable to abuse, especially during crises: we highlight the need to urgently address this issue to preserve the integrity of online conversations.
