The rapid growth in the widespread acceptance and usage of the Internet and the ease of creating online communities have brought advantages in terms of swift access to information alongside ethical problems interrelated with the dark side of the workings of these communities. Relevant research approaching ethics and the dark side of online communities has received widespread publication in a diverse set of journals with a wide variety of objectives and readers that has left its academic contribution broadly fragmented. To help shrink this gap in the literature, this study, through undertaking a systematic review, seeks to map the research on ethics and the dark side of online communities to grasp where the literature has come from and where it is going and, consequently, provide opportunities for future research. This study applied a bibliometric approach based on analysis of the bibliographic coupling with the manual coding of documents to examine the literature on the ethics and the dark side of online communities to set out a holistic framework of its different facets. The content and the thematic analysis of 53 studies identified four thematic groups: quality of the information in online communities, virtual identities, safety in online communities, and the content of online communities. The findings of this study also highlight the various shortcomings in the literature on the ethics and dark side of online communities and lead to some research questions that justify future academic research.

互联网的广泛接受和使用的快速增长以及创建在线社区的便利性带来了快速获取信息方面的优势，同时也带来了与这些社区运作的阴暗面相关的道德问题。涉及道德和在线社区阴暗面的相关研究已在各种期刊上广泛发表，其目标和读者也多种多样，这使得其学术贡献广泛分散。为了帮助缩小文献中的这一差距，本研究通过进行系统回顾，力图绘制有关道德和在线社区阴暗面的研究，以掌握文献的来源和去向，从而提供未来研究的机会。本研究采用基于书目耦合分析和文档手动编码的文献计量方法来检查有关在线社区的道德和阴暗面的文献，以建立其不同方面的整体框架。对 53 项研究的内容和主题分析确定了四个主题组：在线社区信息质量、虚拟身份、在线社区安全以及在线社区内容。这项研究的结果还凸显了有关在线社区的道德和阴暗面的文献中的各种缺陷，并引发了一些为未来学术研究辩护的研究问题。
