Dice.com censorship policy changed in 2011.

It is still possible to find certain discussion posts in 2011 and earlier where censorship complaints were publicly acknowledge by the Dice staff and were not themselves censored.

Here is one such instance:
http://community.dice.com/t5/Customer-Support/Account-suspension/td-p/225388

This alludes to some censorship and account suspensions going on in a deleted post. Although I cannot view the censored posts (which may or may not have violated Dice terms and conditions), this does show that Dice had no moderator policy in place to deny censorship and banning.

Here is another example:
http://community.dice.com/t5/Tech-Market-Conditions/Dice-Censor-back-at-work-protecting-outsourcers/td-p/201716

This poster speaks about an article which was censored for an unknown reason. However his post regarding the censorship was not censored, and neither was his criticism of Dice.

More recently in 2011, any thread even hinting at censorship by Dice in the discussion boards is locked/deleted and the posters are warned or banned - regardless of the lack a rule violation.

Here are two from the past week (the links still come up in search engines but are broken due to deletion by Dice).
Banning and Censorship - Dice Discussions
Vote with your feet if you object to recent censorship

This shows a definitive shift in Dice's unpublished censorship policy. All evidence about where and when censorship occurs is deleted. The bottom line is that dice.com is their website, Dice can ban posts which may tarnish the Dice brand or contradict their statements. However this censorship is a disservice to the IT community. Hopefully someone at Dice will realize the importance of open IT community discussions and reverse their mistake.
