ModPulse WarRoom

ModPulse WarRoom transforms Reddit moderation into a real-time incident response system using threat intelligence, signal correlation, replayable incidents, and AI-assisted moderation workflows.

Inspiration

Modern Reddit moderation is incredibly difficult during coordinated spam waves, brigading events, repost attacks, and abusive behavior bursts. Most moderation workflows still revolve around manually processing isolated reports in chronological queues, forcing moderators to investigate patterns mentally while under pressure.

We wanted to rethink moderation as an operational intelligence problem instead of a simple queue-management problem.

Inspired by incident response systems used in cybersecurity and operations centers, we built ModPulse WarRoom to help moderators detect, correlate, investigate, and respond to coordinated threats in real time directly within Reddit using Devvit.

What it does

ModPulse WarRoom transforms subreddit moderation into a real-time operational incident response workflow.

Instead of flooding moderators with disconnected alerts, the system ingests subreddit activity, generates explainable Threat Signals, and automatically correlates related activity into structured Incidents.

Core capabilities include:

  • Real-time threat signal generation
  • Coordinated abuse and spam detection
  • Incident correlation and escalation
  • AI-assisted investigation summaries
  • Replayable moderation timelines
  • Enriched threat-aware mod queue
  • AutoModerator rule generation
  • Moderator action execution
  • Simulation engine for testing and training

The system helps moderators rapidly understand:

  • what is happening
  • why it is suspicious
  • how severe it is
  • what actions should be taken

without relying on opaque automation.

How we built it

ModPulse WarRoom was built entirely on Reddit's Devvit platform using a modern full-stack TypeScript architecture.

Frontend

  • React 19
  • Vite
  • Tailwind CSS 4
  • Operational SOC-inspired UI design

Backend

  • Hono serverless API architecture
  • Devvit triggers
  • Shared type-safe API contracts
  • Operational event pipeline

Persistence

  • Devvit Redis
  • Sorted-set indexing for incident timelines and signal aggregation
  • Time-series threat correlation logic

Intelligence Pipeline

Incoming posts, comments, and moderation events are routed through a detector framework containing deterministic threat detectors such as:

  • URL coordination detection
  • posting velocity analysis
  • keyword burst detection
  • threat scoring and escalation

Threat Signals are then correlated into Incidents that evolve over time using a severity-based operational state machine.

We also implemented:

  • incident replay infrastructure
  • AI-assisted moderation summaries
  • AutoModerator YAML generation
  • moderation simulation tooling
  • operational onboarding flows
  • resilience-focused error handling

Challenges we ran into

One of the biggest challenges was designing a system that felt operationally intelligent without becoming overly dependent on opaque AI decisions.

We intentionally prioritized deterministic and explainable moderation intelligence over black-box automation. Building reliable signal correlation, incident escalation, and replayable moderation timelines required careful architectural iteration.

Another major challenge was debugging real-time Devvit event pipelines and ensuring incidents persisted correctly across the full moderation workflow.

We also spent significant effort balancing:

  • operational data density
  • moderator usability
  • replay visualization
  • performance
  • reliability under simulated attack conditions

while keeping the experience fully native to Reddit moderation workflows.

Accomplishments that we're proud of

We're especially proud that ModPulse WarRoom evolved beyond a simple moderation dashboard into a genuine operational moderation intelligence platform.

Some highlights include:

  • fully working incident correlation system
  • replayable moderation incidents
  • deterministic threat detection architecture
  • AI-assisted investigation workflows
  • real-time operational dashboards
  • simulation engine for moderator training
  • Devvit-native moderation infrastructure
  • explainable moderation intelligence instead of opaque automation

We're also proud that the platform feels deployable and operational rather than experimental.

What we learned

This project taught us that moderation tooling becomes dramatically more powerful when events are treated as correlated operational incidents rather than isolated queue items.

We learned a great deal about:

  • Devvit serverless architecture
  • operational event pipelines
  • Redis time-series modeling
  • moderation workflow design
  • incident replay systems
  • resilient frontend state handling
  • explainable AI-assisted tooling

Most importantly, we learned how critical moderator trust and operational clarity are in any AI-assisted moderation environment.

What's next for ModPulse WarRoom

We plan to continue evolving ModPulse WarRoom into long-term moderation infrastructure for Reddit communities.

Future roadmap ideas include:

  • advanced detector plugins
  • cross-incident behavioral analysis
  • richer moderator collaboration workflows
  • recurring operational digests
  • advanced replay analytics
  • configurable subreddit defense profiles
  • expanded moderation simulations
  • long-term operational reporting

We also want to deepen integration with Reddit's moderation ecosystem while keeping moderators fully in control of enforcement decisions.

Our long-term vision is to help moderation teams move from reactive queue management to proactive operational threat response.
