User-generated content creates value and risk at the same time. Text, images, audio, profiles, messages, and links can enable participation while also carrying harassment, fraud, sexual exploitation, privacy violations, illegal material, or self-harm concerns. Controls must match the product, audience, reach, and severity of harm.
Decision snapshot
| Decision | Practical approach | Watch for |
|---|---|---|
| Start with product risk | Map who can create, see, share, target, and amplify each content type. | A generic prohibited-content list misses risks created by product mechanics. |
| Layer controls | Combine design limits, automated signals, user reports, human review, and escalation. | No single moderation technique is reliable for every context. |
| Protect the reviewers | Limit exposure, secure tooling, rotate difficult queues, and provide escalation and support. | Moderator wellbeing is part of system safety. |
Map surfaces, actors, and harms
Inventory content types, visibility, audience age, direct contact, resharing, discovery, location, monetization, anonymity, likely abuse, and worst credible outcomes.
Write enforceable rules
Use plain-language definitions and examples, distinguish severity and context, state consequences, explain reporting and appeals, and avoid promising perfect or instant removal.
Design prevention and detection
Use audience and privacy defaults, rate and reach limits, friction for risky actions, block and mute tools, trusted signals, age-appropriate design, and narrowly evaluated automated classifiers.
Build review and escalation operations
Create severity queues, reviewer instructions, evidence controls, response targets, emergency and legal escalation, account-action authorization, appeal independence, and reviewer safety practices.
Measure outcomes and revise
Track prevalence samples, report rates, handling time, reversal, repeat harm, reporter experience, reviewer agreement, and disparate effects. Audit rules after product changes and incidents.
Action checklist
- Every UGC surface has audience, reach, and abuse scenarios mapped
- Rules include examples, severity, consequence, reporting, and appeal information
- Users can block, report, and control relevant visibility
- High-severity cases have an urgent escalation path
- Reviewer access, evidence retention, privacy, and wellbeing are protected
- Metrics include errors and harm prevalence, not only content removed
Working worksheet
Record these fields in the same working document so the decision can be reviewed and handed off:
- Content surface, creator, audience, reach, and persistence
- Harm scenario, severity, likelihood, and affected group
- Preventive design, automated signal, report path, and review queue
- Action, authorization, user notice, appeal, and urgent escalation
- Metric, sampling method, owner, review date, and policy change
Common failure patterns
- Copying community rules from a product with different users and mechanics
- Treating number of removals as proof that harm is decreasing
- Launching private messaging or public discovery without changing the risk model

Moderation is one layer in a broader product risk system. Read review safety across the complete app.
Some harmful exposure can be prevented before moderation. Read minimize evidence and visibility by design.
Moderation records should not persist without purpose. Read set evidence and appeal retention deliberately.
