## In short

- AI is fast and consistent; people understand irony, history and intent.
- Automate clear, low-risk actions; leave bans and appeals to people.
- Send uncertain cases to a review queue instead of guessing.
- Every human decision is feedback that makes the system better.

## Different strengths

| | AI | Human moderators |
|---|---|---|
| Speed | milliseconds, 24/7 | minutes or hours |
| Consistency | same answer every time | depends on the person and the day |
| Nuance | improving, but limited | irony, history between users, intent |
| Scale | thousands of messages per minute | a few hundred per shift |
| Cost of a mistake | can repeat it everywhere | usually isolated |

Neither is enough alone. The goal is to give each one the work it does best.

## A practical split

1. **Automatic, reversible actions** for clear cases with high scores: hide the message, slow down the user, ask them to rephrase.
2. **Review queue** for uncertain scores: a moderator sees the message, its scores and the conversation, and decides.
3. **People only** for serious, hard-to-reverse actions: bans, reports to authorities, decisions about minors.
4. **Appeals** handled by a person who did not take the first decision.

How to set the score bands is explained in [choosing a threshold](https://www.vigimod.com/en/learn/choosing-a-threshold).

## Give moderators the context

A message alone can mislead a person as much as a model. Show the previous messages, the user's history and why the message was flagged (which category, which rule, which score). [Context](https://www.vigimod.com/en/learn/context-in-moderation) helps people too.

## Close the loop

Each human decision is a label: “this was a false alarm”, “this one was missed”. Collected over time, these decisions are the most valuable data to tune thresholds and to improve the next model version.

## Be transparent with users

Tell your community that messages are checked automatically, what happens when a message is flagged and how to appeal. Rules people understand are followed more, and mistakes are forgiven more easily when they can be fixed.

## Protect the moderators

Moderators see the worst content. Automatic filtering of the clearest cases, blurred previews and limits on exposure protect their wellbeing: another reason to let AI handle the first pass.

## Quiz

1. Which action should be left to a person?
   Answer: A permanent ban. Serious, hard-to-reverse actions need human judgement.
2. What should happen to messages with uncertain scores?
   Answer: Send them to a review queue. A person decides where the model is unsure.
3. Why are moderators' decisions valuable data?
   Answer: They show the system's mistakes and can tune thresholds and train the next model. Each decision is a label from the real community.
4. What helps a moderator decide well?
   Answer: Seeing the message, the conversation and why it was flagged. Context helps people as much as models.
