本研究利用 MADOC 数据，分析 Reddit 社区封禁与隔离后 Voat 上的活动及话语变化，发现干预引发异质响应，需区分行为迁移与政策讨论。
AI 中文摘要
平台审核可能扰乱在线社区，但随之而来的响应不一定表现为直接迁移。社区可能搬迁、重组、讨论审核决定、表达审查担忧，或在替代平台上继续活动，而缺乏用户层面迁移的明确证据。本研究考察了 Reddit 社区封禁和隔离及其与 Voat 上活动和迁移相关话语的关系。利用多平台在线社区聚合数据集（MADOC）的数据，我们分析了针对 FatPeopleHate、GreatAwakening、MillionDollarExtreme 和 CringeAnarchy 的干预措施。我们将计算话语筛选与分层独立人工验证程序以及干预前后 90 天窗口内的人口调整估计相结合。结果揭示了异质性的跨平台响应。FatPeopleHate 在 Voat 上的总体活动大幅增加，而政策响应和更广泛相关话语的相对流行度下降。CringeAnarchy 在其永久封禁后直接迁移和政策响应话语均出现下降，尽管部分估计对不确定的人工标签敏感。相比之下，GreatAwakening 表现出政策响应话语的适度增加，而没有明确证据表明直接迁移增加。这些发现表明，平台干预不会产生统一的迁移过程。总体目的地平台活动和迁移相关话语可能朝不同方向发展，这凸显了区分行为迁移与更广泛的关于审核、审查、治理和社区重建讨论的重要性。
英文摘要
Platform moderation can disrupt online communities, but the responses that follow do not necessarily take the form of direct migration. Communities may relocate, reorganize, discuss moderation decisions, express censorship concerns, or continue activity on alternative platforms without clear evidence of user-level movement. This study examines Reddit community bans and quarantines and their relationship with activity and migration-related discourse on Voat. Using data from the Multi-Platform Aggregated Dataset of Online Communities (MADOC), we analyze interventions affecting FatPeopleHate, GreatAwakening, MillionDollarExtreme, and CringeAnarchy. We combine computational discourse screening with a stratified independent human-validation procedure and population-adjusted estimates across 90-day pre- and post-intervention windows. The results reveal heterogeneous cross-platform responses. FatPeopleHate experienced a substantial increase in overall Voat activity while the relative prevalence of policy-response and broader relevant discourse declined. CringeAnarchy showed declines in direct migration and policy-response discourse following its permanent ban, although some estimates were sensitive to uncertain human labels. GreatAwakening instead exhibited a modest increase in policy-response discourse without clear evidence of increased direct migration. These findings suggest that platform interventions do not produce a uniform migration process. Overall destination-platform activity and migration-related discourse may move in different directions, highlighting the importance of distinguishing behavioral migration from broader discussion of moderation, censorship, governance, and community rebuilding.
