# Why Is an Anonymous User Profile Created with an Uninstall Event Linked to a Campaign ID?

> Find out why anonymous user profiles appear with uninstall events tied to campaign IDs, and how to trace the campaign that triggered them.

## Problem

An anonymous user profile is created containing only an uninstall event. It contains no actual user information and does not map to a registered profile.

## Solution

Perform the following steps:

* Expand the uninstall event in the **Activity info** to check for campaign details.
* Locate the **Campaign ID** associated with this event.

* Search for the **Campaign ID** in the dashboard.
* If the campaign was scheduled for **All Users**, it indicates that the user had uninstalled the application before the campaign could be delivered.

Since MoEngage did not receive the proper uninstall callback for this user, a guest profile was created to track this uninstall event. This process ensures that the uninstall event is recorded, even without mapping it to a registered user profile.
