论文摘要
有毒评论是在线经历的仇恨和骚扰的最佳形式。尽管许多研究调查了在线发布的有毒评论的类型，但这种内容对人们的影响以及潜在的防御影响，但没有研究捕获了有毒评论发布或有毒评论如何运行的帐户的长期行为。在本文中，我们提出了一项纵向测量研究，对929k叙述，该研究在18〜个月内就在Reddit上发布有毒评论。这些帐户结合了超过1400万个有毒评论，其中包括侮辱，身份攻击，暴力威胁和性骚扰。我们探讨了这些帐户对Reddit的影响，滥用账户采用的目标策略以及区分滥用账户类别的不同模式。我们的分析构成了基于新的基于时间和图形的功能的基础，这些功能可以改善在线对有毒行为的自动检测，并告知解决每类滥用账户所需的细微干预措施。
Toxic comments are the top form of hate and harassment experienced online. While many studies have investigated the types of toxic comments posted online, the effects that such content has on people, and the impact of potential defenses, no study has captured the long-term behaviors of the accounts that post toxic comments or how toxic comments are operationalized. In this paper, we present a longitudinal measurement study of 929K accounts that post toxic comments on Reddit over an 18~month period. Combined, these accounts posted over 14 million toxic comments that encompass insults, identity attacks, threats of violence, and sexual harassment. We explore the impact that these accounts have on Reddit, the targeting strategies that abusive accounts adopt, and the distinct patterns that distinguish classes of abusive accounts. Our analysis forms the foundation for new time-based and graph-based features that can improve automated detection of toxic behavior online and informs the nuanced interventions needed to address each class of abusive account.
