Zombie post refers to old, outdated posts that continue to circulate on social media days, weeks, months, or even years after their original relevance has faded. Although still visible, this content is essentially "alive but lifeless"—no longer meaningful or timely. The spread of zombie content is a major factor in broken social networking, where platforms feel cluttered, disconnected, and less authentic. This type of content hampers the flow of real-time interactions and is one of the factors contributing to the decline of real and authentic engagements on social networking platforms.
