Flag

Any user is allowed to flag a message. This adds the message to the inbox of your moderation review queue on Stream Dashboard.

client.flagMessage(
  messageId = "message-id",
  reason = "This message is inappropriate",
  customData = mapOf("extra_info" to "more details"),
).enqueue { result -> 
  if (result.isSuccess) {
    // Message was flagged
    val flag: Flag = result.data()
  } else {
    // Handle result.error()
  }
}

client.flagUser(
  userId = "user-id",
  reason = "This user is a spammer",
  customData = mapOf("extra_info" to "more details"),
).enqueue { result ->
  if (result.isSuccess) {
    // User was flagged
    val flag: Flag = result.data()
  } else {
    // Handle result.error()
  }
}

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

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

await client.flagMessage("messageID");

  }
});

// Flag a message
await message.FlagAsync();

// Flag a user
await channelMember.User.FlagAsync();

Reasons & custom data

You can enhance flags by associating them with a specific reason and custom data. It is advisable to utilise a slug or keyword as a designated reason for easy translation or other forms of display customisation.

The custom data can encompass any object, offering supplementary metadata to the flag.

The Query Message Flags endpoint retrieves both reasons and custom data, and the reason can also be utilised for filtering these flags.

// flag with a reason
let flag = await client.flagMessage(messageID, {
  reason: "spammy_user",
});

// flag with a reason and additional custom data
flag = await client.flagMessage(messageID, {
  reason: "spammy_user",
  custom: {
    user_comment: "This user is spamming the homepage.",
    page: "homepage",
  },
});

// flag with only custom data
flag = await client.flagMessage(messageID, {
  custom: {
    page: 'homepage',
  },
});
cf

// flag with a reason
messageController.flag(reason: "spammy_user")

Query Flagged Messages

If you prefer to build your own in-app moderation dashboard, rather than use the Stream dashboard, you can query flagged messages using the QueryReviewQueue API endpoint.

Both server-authenticated and user-authenticated clients can use this method. For client-side requests, the user needs moderator or admin permissions.

const response = await client.moderation.queryReviewQueue(
    { entity_type: "stream:chat:v1:message" },
    [{ field: "created_at", direction: -1 }],
    { next: null }
)

for (const item of response.items) {
	console.log(item.message.id)
	console.log(item.message.text)
	console.log(item.message.type)
	console.log(item.message.created_at)
}

console.log(next) // <-- next cursor for pagination

Please refer to the Moderation API documentation for more details.

Mutes

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

client.muteUser("user-id").enqueue { result ->
  if (result.isSuccess) {
    // User was muted
    val mute: Mute = result.data()
  } else {
    // Handle result.error()
  }
}

client.unmuteUser("user-id").enqueue { result ->
  if (result.isSuccess) {
    // User was unmuted
  } else {
    // Handle result.error()
  }
}

// client-side mute
const mute = await client.muteUser('eviluser');

// client-side mute for 60 minutes
const mute = await client.muteUser('eviluser', null, {
  timeout: 60
});

// server-side mute requires the id of the user creating the mute as well
const mute = await client.muteUser('eviluser', 'user_id');

// 

$mute = $client->muteUser('evil-user', 'user-id');

await client.muteUser("eviluser");

await client.unmuteUser("eviluser");

import StreamChat

let userController = chatClient.userController(userId: "another_user")

/// 1: Call `ChatUserController.mute` to mute the user.
userController.mute { error in
  // handle possible errors
  print(error ?? "user muted")
  
  /// 2: Call `ChatUserController.unmute` to unmute the user.
  userController.unmute { error in
    print(error ?? "user unmuted")
  }
}

Client->MuteUser(User);

Client->UnmuteUser(User);

# server-side mute requires the id of the user creating the mute as well
client.mute_user(target_user["id"], server_user["id"])

# server-side mute requires the id of the user creating the mute as well
client.mute_user(target_user["id"], server_user["id"])

// server-side mute requires the id of the user creating the mute as well
client.MuteUser(ctx, targetUser.ID, serverUser.ID)

// server-side mute requires the id of the user creating the mute as well
await userClient.MuteAsync(targetUser.Id, serverUser.Id);

// Mute a user
await channelMember.User.MuteAsync();

// Unmute previously muted user
await channelMember.User.UnmuteAsync();

// Mute a channel
await channel.MuteChannelAsync();

// Mute previously muted channel
await channel.UnmuteChannelAsync();

client.muteUser("user-id").enqueue(result -> {
  if (result.isSuccess()) {
    // User was muted
    Mute mute = result.data();
  } else {
    // Handle result.error()
  }
});

client.unmuteUser("user-id").enqueue(result -> {
  if (result.isSuccess()) {
    // User was unmuted
  } else {
    // Handle result.error()
  }
});

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

Ban

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

Channel watchers cannot be banned.

It is also possible to ban the user’s last known IP address to prevent the creation of new “throw-away” accounts. This type of ban is only applicable on the app level. ISPs often rotate IP addresses, therefore in order to prevent innocent users to be banned, we automatically apply a 30 day timeout when applying an IP ban. This value can be overwritten, if a timeout is supplied in the request. 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.

// Ban user for 60 minutes from a channel
channelClient.banUser(targetId = "user-id", reason = "Bad words", timeout = 60).enqueue { result ->
  if (result.isSuccess) {
    // User was banned
  } else {
    // Handle result.error()
  }
}

channelClient.unBanUser(targetId = "user-id").enqueue { result ->
  if (result.isSuccess) {
    // User was unbanned
  } else {
    // Handle result.error()
  }
}

// ban a user for 60 minutes from all channel
let data = await client.banUser('eviluser', {
  banned_by_id: userID, // ID of the user who is performing the ban (Server-side auth)
  timeout: 60,
  reason: 'Banned for one hour',
});

// ban a user and their IP address for 24 hours
let data = await client.banUser('eviluser', {
  banned_by_id: userID,
  timeout: 24*60,
  ip_ban: true,
  reason: 'Please come back tomorrow',
});

// ban a user from the livestream:fortnite channel
data = await channel.banUser('eviluser', {
  banned_by_id: userID,
  reason: 'Profanity is not allowed here',
});

// remove ban from channel

Query Banned Users

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.

// Retrieve the list of banned users

  QueryUsersRequest(

// Query for banned members from one channel
client.queryBannedUsers(filter = Filters.eq("channel_cid", "ChannelType:ChannelId")).enqueue { result ->
  if (result.isSuccess) {
    val bannedUsers: List<BannedUser> = result.data()
  } else {
    // Handle result.error()
  }
}

// retrieve the list of banned users
const response = await client.queryUsers({banned:true}, {}, {limit:10, offset:0});

// query for banned members from one channel
const results = await client.queryBannedUsers({channel_cid: "livestream:123"});

// retrieve the list of banned users
await client.queryUsers(
  filter: Filter.equal('banned', true),

Query Bans Endpoint

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.

Available fields

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 on the first page. Ordering can be reversed using the sort option.

// Get the bans for channel livestream:123 in descending order
client.queryBannedUsers(
  filter = Filters.eq("channel_cid", "livestream:123"),
  sort = QuerySortByField.descByName("createdAt"),

Shadow Ban

Instead of a default ban, you can *shadow ban *users from a channel, set of channels, or an entire App. When a user is shadow banned, they will still be allowed to post messages, but any message sent during the ban will only be visible to the author of the message and invisible to other users of the App.

Shadow banning can delay a persistent bad actor from attempting ban evasion techniques by obfuscating the fact that a ban has occurred for them. Since a shadow ban’s effectiveness relies on it not being discovered, shadow bans work best in chats with a high volume of messages and fast velocity where the offending user’s messages not receiving engagement appears plausible; think livestreams.

Messages from a shadow banned user will include the shadowed: true flag on the message object. This flag is only visible to users other than the shadow banned user, so the offender will not be able to recognize that they are shadow banned even if they use developer tools to inspect responses from the API. You will need to implement UI logic for how your application will handle shadowed messages. Having the client hide these messages for everybody other than the user sending them is a common approach.

// Shadow ban user for 60 minutes from a channel
channelClient.shadowBanUser(targetId = "user-id", reason = "Bad words", timeout = 60).enqueue { result ->
   if (result.isSuccess) {
     // User was shadow banned
   } else {
     // Handle result.error()
   }
}

channelClient.removeShadowBan("user-id").enqueue { result ->
  if (result.isSuccess) {
    // Shadow ban was removed
  } else {
    // Handle result.error()
  }
