# Legacy Moderation Extensions

<Warning>
  These extensions are considered legacy and are scheduled for deprecation. They are no longer recommended for new integrations and will not receive feature updates or enhancements.

  For new projects, use [AI Moderation](/moderation/overview).
</Warning>

## Slow Mode

Slow down messages in groups to make them legible during high-traffic events.

When enabled in a group, participants can only send messages after configured intervals. Admins and moderators are not restricted.

**Enable Slow Mode**

```js theme={null}
CometChat.callExtension('slow-mode', 'POST', 'v1/configure', {
  "guid": "cometchat-guid-1",
  "slowDownTimeInMS": 660000
}).then(response => {
  // Success
}).catch(error => {
  // Error
});
```

**Disable Slow Mode**

```js theme={null}
CometChat.callExtension('slow-mode', 'DELETE', 'v1/configure', {
  "guid": "cometchat-guid-1"
}).then(response => {
  // Success
}).catch(error => {
  // Error
});
```

**Fetch Slow Mode Details**

```js theme={null}
const guid = "cometchat-guid-1";
CometChat.callExtension('slow-mode', 'GET', `v1/fetch-configuration?guid=${guid}`, null)
  .then(response => {
    // { isSlowed, slowDownTimeInMS, lastMessageSentAtTimestamp }
  });
```

***

## Report User

Enables users to report other users for offensive or suspicious behavior.

**Settings**

1. Go to **Extensions** → Enable **Report User**
2. Configure moderation criteria (max reports before notification)
3. Set up webhook URL for reports

**Report a User**

```js theme={null}
CometChat.callExtension('report-user', 'POST', 'v1/report', {
  "uid": "cometchat-uid-3",
  "reason": "Misbehaving",
  "guid": "cometchat-guid-1" // Optional: only for group reports
}).then(response => {
  // { success: true }
});
```

**View Reports**

Open the Extension's settings page and click "View Reports" to take action (Kick, Ban, Block, or Ignore).

***

## Report Message

Enable users to report messages in conversations.

**Report a Message**

```js theme={null}
CometChat.callExtension('report-message', 'POST', 'v1/report', {
  "msgId": 123,
  "reason": "Contains profanity"
}).then(response => {
  // { success: true }
});
```

**View Reports**

Open the Extension's settings page and click "View Reports" to Delete or Ignore reported messages.

***

## Data Masking Filter

Hide phone numbers, email addresses, and other sensitive information in messages.

**Settings**

1. Enable the extension
2. Configure default masks (Emails, SSN, US phone numbers)
3. Add custom regex patterns for additional masking

**Response Format**

```json theme={null}
{
  "@injected": {
    "extensions": {
      "data-masking": {
        "data": {
          "sensitive_data": "yes",
          "message_masked": "My number is ***** & my email id is ****"
        }
      }
    }
  }
}
```

**Implementation**

```js theme={null}
var metadata = message.getMetadata();
if (metadata != null) {
  var injectedObject = metadata["@injected"];
  if (injectedObject?.extensions?.["data-masking"]) {
    var dataMaskingObject = injectedObject.extensions["data-masking"]["data"];
    var message_masked = dataMaskingObject["message_masked"];
  }
}
```

***

## Profanity Filter

Mask or hide profanity in messages using a customizable blacklist.

**Settings**

1. Enable the extension
2. Optionally enable "Drop messages with Profanity"
3. Add comma-separated list of words to filter (supports emojis)

**Response Format**

```json theme={null}
{
  "@injected": {
    "extensions": {
      "profanity-filter": {
        "profanity": "yes",
        "message_clean": "This is ****"
      }
    }
  }
}
```

**Implementation**

```js theme={null}
var metadata = message.getMetadata();
if (metadata != null) {
  var injectedObject = metadata["@injected"];
  if (injectedObject?.extensions?.["profanity-filter"]) {
    var profanityFilterObject = injectedObject.extensions["profanity-filter"];
    var cleanMessage = profanityFilterObject["message_clean"];
  }
}
```

***

## Image Moderation

AI-powered image moderation to detect unsafe content.

Images are classified into:

* Explicit Nudity
* Suggestive Nudity
* Violence
* Visually Disturbing

**Response Format**

```json theme={null}
{
  "@injected": {
    "extensions": {
      "image-moderation": {
        "unsafe": "yes",
        "confidence": "99",
        "category": "explicit_nudity"
      }
    }
  }
}
```

A confidence value less than 50 is likely a false-positive.

**Implementation**

```js theme={null}
const metadata = message.getMetadata();
if (metadata != null) {
  const injectedObject = metadata["@injected"];
  if (injectedObject?.extensions?.["image-moderation"]) {
    const { attachments } = injectedObject.extensions["image-moderation"];
    for (const attachment of attachments) {
      if (!attachment.error) {
        const { unsafe } = attachment.data.verdict;
      }
    }
  }
}
```

***

## Sentiment Analysis

Understand the tone or sentiment of messages.

Messages are classified as: Positive, Neutral, Negative, or Mixed.

Supported languages: German, English, Spanish, Italian, Portuguese, French, Japanese, Korean, Hindi, Arabic, Chinese (simplified & traditional)

**Response Format**

```json theme={null}
{
  "@injected": {
    "extensions": {
      "sentiment-analysis": {
        "sentiment": "positive",
        "sentiment_score": {
          "positive": 95,
          "neutral": 4,
          "negative": 0,
          "mixed": 0
        }
      }
    }
  }
}
```

***

## In-Flight Message Moderation

Manually moderate messages before delivery.

**Settings**

Configure moderation criteria:

* Moderate all messages, one-on-one only, or group only
* Moderate messages from specific users (UIDs)
* Moderate messages to specific users or groups

**Actions**

From the Dashboard, you can:

* **Approve**: Send the message to the receiver
* **Reject**: Delete the message
* **Kick**: Remove user from group (can rejoin)
* **Ban**: Ban user from group (cannot rejoin)

***

## Virus & Malware Scanner

Scan uploaded files for malicious content using [Scanii](https://scanii.com).

**Prerequisites**

Create a Scanii account and get your API Key and Secret.

**Response Format**

```json theme={null}
{
  "@injected": {
    "extensions": {
      "virus-malware-scanner": {
        "attachments": [{
          "data": {
            "url": "https://media.com/file.mp3",
            "verdict": {
              "scan_results": []
            }
          },
          "error": null
        }]
      }
    }
  }
}
```

An empty `scan_results` array means the file is safe.

***

## XSS Filter

Sanitize messages to prevent cross-site scripting attacks. Applicable only for Web SDK.

**Response Format**

```json theme={null}
{
  "@injected": {
    "extensions": {
      "xss-filter": {
        "hasXSS": "yes",
        "sanitized_message": "<sanitized content>"
      }
    }
  }
}
```

**Implementation**

```js theme={null}
var metadata = message.getMetadata();
if (metadata != null) {
  var injectedObject = metadata["@injected"];
  if (injectedObject?.extensions?.["xss-filter"]) {
    var xssFilterObject = injectedObject.extensions["xss-filter"];
    var sanitized_message = xssFilterObject["sanitized_message"];
  }
}
```
