Conclusion, Acknowledgments, References, and Competing interests
Reddit is a popular news aggregation, content rating, and discussion website founded in 2005. Bots on Reddit provide internal moderation and communication, augment functionality (e.g., for mobile users), or post content, ranging from comic and playful posts by evident automated accounts such as haiku robot and ObamaRobot, to trolling and provocative comments by undercover social bots[214].
Similarly to Wikipedia, Reddit has developed norms and protocols for deploying bots [215], but similarly to Twitter, it has no effective service limitations to prevent covert and malicious automated accounts. Nevertheless, Reddit differs from Twitter in several crucial ways – content on the site is posted within communities, heavily moderated, up-/downvoted, and extensively discussed. Due to these structural differences, political misinformation, polarization, and conflict are less pronounced on the platform.
Reddit offers evidence for collaboration and contagion between humans and bots. Content moderators have widely adopted Automod – a bot that is flexible to updates, adaptable to community rules, and interpretable. The bot aids with menial tasks but does not necessarily decrease workloads as it requires continuous updates in response to changes in user behavior and language and involves high volumes of correspondence with incorrectly banned users [216].
On the other side, regular users engage with evident entertainment bots, and their direct replies imitate the sentiment and the words of the bot posts [217]. Thus, emotional contagion and lexical entrainment can occur between humans and bots, even when humans are aware of the simple automated script behind the bot.
