This sort of activity and behavior is common on sites like reddit. It's used by media companies and brands, especially as the reach is much bigger than HN comments.
Astroturfing is big business and can be very profitable. An account itself isn't worth much, it's the overall execution that matters.
I'd love to see HN or Reddit or someone work with the feds on how to investigate and prosecute astroturfing/sockpuppets/shilling, perhaps as unauthorized computer access and/or fraud.
Astroturfing and shilling isn’t illegal. Unless an account was hacked, no crime has been committed. Even lying generally isn’t a crime. In terms of fraud, there has to be a determination of unlawful gain or to deprive a victim of a legal right. Astroturfing isn’t fraud, nor is shilling.
