Researchers have suggested that "the Manosphere," a conglomerate of men-centered online communities, may serve as a gateway to far right movements. In that context, this paper quantitatively studies the migratory patterns between a variety of groups within the Manosphere and the Alt-right, a loosely connected far right movement that has been particularly active in mainstream social networks. Our analysis leverages over 300 million comments spread through Reddit (in 115 subreddits) and YouTube (in 526 channels) to investigate whether the audiences of channels and subreddits associated with these communities have converged between 2006 and 2018. In addition to subreddits related to the communities of interest, we also collect data on counterparts: other groups of users which we use for comparison (e.g., for YouTube we use a set of media channels). Besides measuring the similarity in the commenting user bases of these communities, we perform a migration study, calculating to which extent users in the Manosphere gradually engage with Alt-right content. Our results suggest that there is a large overlap between the user bases of the Alt-right and of the Manosphere and that members of the Manosphere have a bigger chance to engage with far right content than carefully chosen counterparts. However, our analysis also shows that migration and user base overlap varies substantially across different platforms and within the Manosphere. Members of some communities (e.g., Men's Rights Activists) gradually engage with the Alt-right significantly more than counterparts on both Reddit and YouTube, whereas for other communities, this engagement happens mostly on Reddit (e.g., Pick Up Artists). Overall, our work paints a nuanced picture of the pipeline between the Manosphere and the Alt-right, which may inform platforms' policies and moderation decisions regarding these communities.

反女权主义社区是通往最右边的门户吗？来自Reddit和YouTube的证据

研究人员建议，以男性为中心的在线社区的联合体“ The Manosphere”可以作为通向极右运动的门户。在这种情况下，本文定量研究了Manosphere和Alt-right之间的各种迁徙模式，Alt-right是一种松散连接的极右运动，在主流社交网络中特别活跃。我们的分析利用了通过Reddit（在115个子书签中）和YouTube（在526个频道中）传播的3亿多条评论来调查与这些社区相关的频道和子书签的受众在2006年至2018年之间是否趋同。有兴趣的话，我们还会收集与之对应的数据：我们用于比较的其他用户组（例如，对于YouTube，我们使用一组媒体渠道）。除了衡量这些社区的评论用户群的相似性之外，我们还进行了迁移研究，计算了Manosphere中的用户逐渐使用Alt-right内容的程度。我们的结果表明，Alt-right和Manosphere的用户群之间存在很大的重叠，并且Manosphere成员比精心选择的同行有更大的机会参与最右边的内容。然而，我们的分析还表明，迁移和用户群重叠在不同平台之间以及在Manosphere内都存在很大差异。与Reddit和YouTube上的社区成员相比，某些社区的成员（例如，男性权利激进主义者）与Alt右派的互动逐渐增多，而对于其他社区，这种参与主要发生在Reddit上（例如，Pick Up Artists）。总体而言，我们的工作描绘了Manosphere和Alt-right之间管道的细微差别，这可能会为平台关于这些社区的政策和适度决策提供依据。
