Linguistics identifies anonymous users

mask.of.sanity writes: Researchers have examined writing styles to identify previously anonymous carders and hackers operating on underground forums.
Up to 80 percent of users who wrote at least 5000 words across their posts could be identified using linguistic techniques.
The techniques such as stylometric analysis were used to track users who posted across different forums, and could even be used to unveil authors of thesis papers or blogs who had taken to underground networks.
