Report offensive messages

PubNub provides a mechanism for users to report offensive content in messages directly from their applications. A moderator can then fetch these flagged messages from Message Persistence and either delete them or take appropriate action against the users who sent the messages.

User ID / UUID

User ID is also referred to as UUID/uuid in some APIs and server responses but holds the value of the userId parameter you set during initialization.

Flag Messages

Use the addMessageAction method to add a flag as an action to a published message. The flag is stored and linked to the original message, so you can see if messages are flagged or not when you fetch them from Message Persistence.

JavaScript

pubnub.addMessageAction(
  {
    channel: 'ch-1'
    messageTimetoken: '15610547826970040',
    action: {
      type: 'flagged',
      value: 'message is inappropriate',
    },
  },
  function(status, response) {

  }
);

Swift

extension MyAppMessageAction: MessageAction {}

let action = MyAppMessageAction(type: "flagged", value: "message is inappropriate")

pubnub.addMessageAction(
  channel: "ch-1",
  message: action,
  messageTimetoken: 15610547826969050
) { result in
  switch result {
  case let .success(response):
    print("Successfully Message Action Add Response: \(response)")
  case let .failure(error):
    print("Error from failed response: \(error.localizedDescription)")
  }

Unflag Messages

Use the removeMessageAction method to remove a flag from a message.

JavaScript

pubnub.removeMessageAction(
{
    channel: 'ch-1'
    messageTimetoken: '15610547826970040',
    actionTimetoken: '15610547826970040',
},
function(status, response) {
}
);

Swift

pubnub.removeMessageActions(
  channel: "ch-1",
  message: 15610547826969050,
  action: 15610547826970050
) { result in
  switch result {
  case let .success(response):
    print("Successfully Message Action Remove Response: \(response)")
  case let .failure(error):
    print("Error from failed response: \(error.localizedDescription)")
  }
})

Java

pubnub.removeMessageAction()
    .channel("ch-1")
    .messageTimetoken(15701761818730000L)
    .actionTimetoken(15701775691010000L)
    .async(result -> { /* check result */ });

Unity

pubnub.RemoveMessageActions().ActionTimetoken(15701775691010000).Channel("ch-1").MessageTimetoken(15701761818730000).Async((result, status) => {
        if (!status.Error) {
            // result has no actionable data
        } else {
            Debug.Log(status.Error);
            Debug.Log(status.ErrorData.Info);
        }
});

Flagging Events

PubNub triggers events when flags are added or removed. Users that are subscribed to channels will receive these events.

Message action added:

{
   "channel":"my_channel",
   "subscription":null,
   "timetoken":"15871508399473609",
   "publisher":"user-1",
   "message":{
      "source":"actions",
      "version":"1.0",
      "action":"added",
      "data":{
         "type":"flagged",
         "value":"message is inappropriate",
         "messageTimetoken":"15632184115444390",
         "actionTimetoken":"15632184115444394"
