Comments on the Huffington Post (HP) that are perfectly in compliance with the site’s published policies are regularly censored. Over the last four months we have documented examples of this out of control censorship on the blog:

The many examples documented on this blog are just the tip of the iceberg.  For each example there are thousands more.  These examples reveal a pattern of arbitrary censorship extending far beyond HP's published moderation policies.  Specific patterns of censorship include:
 
* Censorship by Artificial Intelligence program. Although HP has never discussed it openly, moderators have told us via email that the site uses an AI system to pre-screen comments. This AI system regularly censors comments that in no way violate the site’s published standards.

* Censorship to stifle criticism.  Some HP authors practice routine censorship of comments that point out errors in their reasoning or offer alternative points of view. Specific authors who do this on a regular basis include Depak Chopra, Amy Suskind, and Robert Lanza.

Censorship of comments about the Huffington Post. Any comment that discusses the censorship policy of the site or other issues about how the site is run are almost certain to be censored.
