What tools does Reddit provide to detect coordinated inauthentic behavior?

Reddit provides moderators and admins with a set of native tools for identifying and responding to coordinated inauthentic behavior, though the most powerful detection capabilities remain at the admin level rather than being fully accessible to individual community moderators. For moderators, the primary tool is the mod log, which records every moderation action taken in the subreddit along with timestamps and the moderating account. This historical record allows mods to identify unusual patterns in the timing and volume of reports, removals, and content from specific accounts. The contributor list and banned users list, accessible through Mod Tools, provide a consolidated view of account activity in the subreddit that can help identify accounts acting in coordination when reviewed alongside post timing data. Reddit's Spam filter, which operates behind the scenes on all communities, uses behavioral signals including posting velocity, account age, IP patterns, and content similarity to flag likely spam and bot accounts automatically. Posts caught by the spam filter land in the modqueue rather than in the visible feed, which is why maintaining a consistent modqueue review practice is important for catching this activity before it affects the community. At the admin level, Reddit has dedicated Trust and Safety teams that investigate coordinated behavior at scale, including vote manipulation rings, astroturfing campaigns, and brigades across multiple communities. Moderators who identify a pattern of behavior that appears organized and crosses multiple subreddits or involves significant rule violations should report it to Reddit admins through the subreddit's modmail by messaging r/reddit.com or through the admin contact channels. Providing specific evidence — account names, timestamps, post links, and a clear description of the pattern — makes the investigation significantly more actionable than a general complaint. Third-party tools like RedditMetis and user history analysis tools help moderators examine individual account histories in detail, making it easier to assess whether an account's behavior looks authentic or scripted.
