Flag

Copied!

Any user is allowed to flag a message.

const flag = await client.flagMessage(messageResponse.message.id);

$flag = $client->flagMessage('message-id', ['user_id' => 'user-id']);

await client.flagMessage("messageID");

Mutes

Copied!

Any user is allowed to mute another user. Mutes are stored at user level and returned with the rest of the user information when connectUser is called. A user will be be muted until the user is unmuted or the mute is expired.

    } 
}

After muting a user messages will still be delivered via web-socket. Implementing business logic such as hiding messages from muted users or display them differently is left to the developer to implement.

Messages from muted users are not delivered via push (APN/Firebase)

Ban

Copied!

Users can be banned from an app entirely or from a channel. When a user is banned, it will not be allowed to post messages until the ban is removed or expired but it will be able to connect to Chat and to channels as before.

It is also possible to ban the user's last known IP address to prevent creation of new "throw-away" accounts. This type of ban is only applicable on the app level. We do not recommend applying IP ban without reasonable timeout, however this is not restricted. The IP address will be unbanned either after reaching a timeout or with explicit user unban.

In most cases only admins or moderators are allowed to ban other users from a channel.

Banning a user from all channels can only be done using server-side auth.

Query Banned Users

Copied!

Banned users can be retrieved in different ways:

  1. Using the dedicated query bans endpoint

  2. User Search: you can add the banned:true condition to your search. Please note that this will only return users that were banned at the app-level and not the ones that were banned only on channels.

        List<User> users = result.data(); 
    } else { 
        // Handle result.error() 
    } 
});

Query Bans Endpoint

Copied!

The query bans endpoint allows you to list bans for your application. Similar to other query endpoints, you can filter bans by different fields and control the ordering of results.

Globally banned users can only be retrieved using server-side auth

Available fields

Copied!

Name

Description

Example

Operators

channel_cid

The channel CID for the ban. When this parameter is not provided, both global and channel bans will be returned.

{ channel_cid :{$in:["livestream:1","livestream:2"]}}

$eq, $in

user_id

The ID of the banned user

{ user_id: "evil_user" }

$eq, $in, $neq, $nin

expired

The date (RFC339) of the ban expiration

{ expired: {$gt: "2020-10-02T15:00:00Z"} }

$eq, $gt, $gte, $lt, $lte

created_at

The date (RFC339) of the ban creation

{ created_at: {$gt: "2020-10-02T15:00:00Z"} }

$eq, $gt, $gte, $lt, $lte

banned_by_id

The ID of the user that created the ban

{ banned_by_id: "42"}

$eq, $in, $neq, $nin

Pagination for bans can be done in two ways: using offset/limit or using the "created_at" field. Bans are returned in ascending order by default so to get the second page you need to request bans with "created_at" less than the created_at of the last ban in the first page. Ordering can be reversed using the sort option.

// get the bans for channel livestream:123 in descending order 
const response = await client.queryBannedUsers({channel_cid: "livestream:123"}, {created_at: -1}); 
 
// get the next page of bans for the same channel 
await client.queryBannedUsers( 
   { channel_cid: "livestream:123", created_at_before_or_equal: createdAt }, 
   { created_at: -1 } 
);

Shadow Ban

Copied!

Users can be shadow banned from an app entirely or from a channel. When a user is shadow banned, it will still be allowed to post messages, but any message sent during, will have shadowed: true field. However, this will be invisible from the author of the message.

It's up to the client-side implementation to hide or otherwise handle these messages appropriately.

Administrators can view shadow banned user status in queryChannels(), queryMembers() and queryUsers().

Automod

Copied!

For livestream and gaming channel types Automod is enabled by default. There are three options for moderation:

  • disabled
  • simple (blocks messages that contain a list of profane words)
  • ai (uses an AI-based classification system to detect various types of bad content)
AI-based moderation is a premium feature. Please contact sales to discuss your options.
