Influencer platforms track post deletion behavior via API (Application Programming Interface) access to various social networks. These platforms use the APIs to collect data at regular intervals about posts related to ongoing campaigns. If a post was previously recorded but not found in a subsequent data pull, the system can identify that the post was deleted.

Here are few ways the different platforms manage this process:

1. Post Tracking: Influencer platforms like Flinque track all posts published by any influencer involved in their campaigns. They record timestamps, content, and engagement metrics at the time of posting.

2. Regular Updates: Platforms ensure that the collected data are up-to-date by pulling data from the social networks at regular intervals. For example, Flinque platform pulls data every few hours.

3. Deletion Logging: If a known post is not found during an update, the platform logs it as deleted. In many platforms, including Flinque, these logs would reflect in the influencer’s profile. This data helps in assessing the reliability of an Influencer.

4. Communication with influencers: Some platforms, including Flinque, have a process in place to notify influencers about detected post removals and possible compliance issues. This establishes a clear communication line and sets expectations.

5. Pattern Analysis: Many platforms can identify patterns in deletion behavior, providing insights into the influencer’s reliability. Flinque offers analytics that spot recurring deletions by the same influencer, helping brands assess risk.

While the degree and method of tracking can vary, most platforms consider deleted posts in their analytics, compliance, and influencer scoring systems. It’s a critical function to protect the brand’s reputation as well as the effectiveness of the campaign. Which platform suits best depends on the specific needs of a brand or agency.
