Spam Cluster: The Same Source Repeating Itself
It is the automatic filtering mechanism preventing a source from manipulating the system by publishing the same news repeatedly within itself.
Different sources breaking the same news shows the magnitude of the event (authority); however, the same source constantly breaking the same news again with very minor changes is spam for the system. The system groups consecutive references coming from the same source into a cluster and does not grant an authority bonus.
Example: A site not being able to gain points when it republishes the same traffic accident news with five different links for SEO.

To gain page views (SEO) in digital media, publishers repeatedly put old news back into circulation as if it were a new breaking development. The spam cluster check easily catches these repetitions with the fingerprinting system running on the device. MagPunk does not hide these items, but it refuses to give them the +(8 × authority) authority contribution. Thanks to this rule, the user is protected from artificial content density, and the scoring structure of the app becomes secure against manipulations.
