ABSTRACT:
Chain-letters within user-generated comments on a website are detected based on an inserted watermark. Comments identified as likely chain-letters are rendered for display with the inserted watermark. When a user propagates a chain-letter by copying and pasting a comment already rendered on the website with the inserted watermark, the inserted watermark is recognized, and a spam score associated with the comment is adjusted. Those comments with spam scores above a pre-defined threshold are displayed on the website in an altered format.
