Abstract summary: We report the results of a large-scale observational study of how problematic online communities progress following community-level moderation measures. Our results suggest that, in both cases, moderation measures significantly decreased posting activity on the new platform. In spite of that, users in one of the studied communities showed increases in signals associated with toxicity and radicalization.

Abstract: When toxic online communities on mainstream platforms face moderation measures, such as bans, they may migrate to other platforms with laxer policies or set up their own dedicated websites. Previous work suggests that within mainstream platforms, community-level moderation is effective in mitigating the harm caused by the moderated communities. It is, however, unclear whether these results also hold when considering the broader Web ecosystem. Do toxic communities continue to grow in terms of their user base and activity on the new platforms? Do their members become more toxic and ideologically radicalized? In this paper, we report the results of a large-scale observational study of how problematic online communities progress following community-level moderation measures. We analyze data from r/The_Donald and r/Incels, two communities that were banned from Reddit and subsequently migrated to their own standalone websites. Our results suggest that, in both cases, moderation measures significantly decreased posting activity on the new platform, reducing the number of posts, active users, and newcomers. In spite of that, users in one of the studied communities (r/The_Donald) showed increases in signals associated with toxicity and radicalization, which justifies concerns that the reduction in activity may come at the expense of a more toxic and radical community. Overall, our results paint a nuanced portrait of the consequences of community-level moderation and can inform their design and deployment.

Taming Toxicity or Fueling It? The Great Ban`s Role in Shifting Toxic User Behavior and Engagement [0.6918368994425961]
We evaluate the effectiveness of The Great Ban, one of the largest deplatforming interventions carried out by Reddit. We analyzed 53M comments shared by nearly 34K users. We found that 15.6% of the moderated users abandoned the platform while the remaining ones decreased their overall toxicity by 4.1%.

We study the first NLP study dedicated to detecting norm violations in conversations on live-streaming platforms. We define norm violation categories in live-stream chats and annotate 4,583 moderated comments from Twitch. Our results show that appropriate contextual information can boost moderation performance by 35%.

Online conspiracy communities are more resilient to deplatforming [2.9767849911461504]
We compare the shift in behavior of users affected by the ban of two large communities on Reddit, GreatAwakening and FatPeopleHate. We estimate how many users migrate, finding that users in the conspiracy community are much more likely to leave Reddit altogether and join Voat. Few migrating zealots drive the growth of the new GreatAwakening community on Voat, while this effect is absent for FatPeopleHate.

Understanding Online Migration Decisions Following the Banning of Radical Communities [0.2752817022620644]
We study how factors associated with the RECRO radicalization framework relate to users' migration decisions. Our results show that individual-level factors, those relating to the behavior of users, are associated with the decision to post on the fringe platform.

We show that participating in fringe communities on Reddit increases users' toxicity and involvement with subreddits similar to the banned community. In short, we find evidence for a spillover of antisocial behavior from fringe platforms onto Reddit via co-participation.

One of Many: Assessing User-level Effects of Moderation Interventions on r/The_Donald [1.1041211464412573]
We evaluate the user level effects of the sequence of moderation interventions that targeted r/The_Donald on Reddit. We find that interventions having strong community level effects also cause extreme and diversified user level reactions. Our results highlight that platform and community level effects are not always representative of the underlying behavior of individuals or smaller user groups.

We investigate the effect of annotator identities (who) and beliefs (why) on toxic language annotations. We consider posts with three characteristics: anti-Black language, African American English dialect, and vulgarity. Our results show strong associations between annotator identity and beliefs and their ratings of toxicity.

News consumption and social media regulations policy [70.31753171707005]
We analyze two social media that enforced opposite moderation methods, Twitter and Gab, to assess the interplay between news consumption and content regulation. Our results show that the presence of moderation pursued by Twitter produces a significant reduction of questionable content. The lack of clear regulation on Gab results in the tendency of the user to engage with both types of content, showing a slight preference for the questionable ones which may account for a dissing/endorsement behavior.

Echo Chambers on Social Media: A comparative analysis [64.2256216637683]
We introduce an operational definition of echo chambers and perform a massive comparative analysis on 1B pieces of contents produced by 1M users on four social media platforms. We infer the leaning of users about controversial topics and reconstruct their interaction networks by analyzing different features. We find support for the hypothesis that platforms implementing news feed algorithms like Facebook may elicit the emergence of echo-chambers.
