In the case of anonymous and pseudonymous works, other than those referred to in paragraph (1) above, the publisher whose name appears on the work shall, in the absence of proof to the contrary, be deemed to represent the author, and in this capacity be shall be entitled to protect and enforce the author's rights. The provisions of this paragraph shall cease to apply when the author reveals his identity and establishes his claim to authorship of the work.
So the anonymous authors rights now have to be protected and enforced, which I would assume means that the work stays with all rights reserved.
For if the author reveals himself, and a license has been placed on their work that has (given) some rights away at least in the context of a public domain type license then this would not have been a act of enforcing and protecting the rights.
I think a CC license with the noncommercial clause would be more appropriate in this situation rather than with out one just for the sake of being really safe. The whole purpose of a copyright is to help the author secure the value of that work. I expect the only reason someone would become angry or upset is if the work generated revenue with out their consent.
I mean all you are supposed to do is
protect and
enforce their rights. So the protect them you do not license them out. To enforce them you report copyright violations on their behalf if you know about them...until the author reveals himself or you delete/burn the copyrighted material and free you're self from having to worry over such stuff.
Or, we just use a restrictive license and make a best effort to protect the contributions, and stop trying to leave loop holes for our own self gain.
Ok that last sentence was a little over board, but come on. Just lock the content down unless the author(s) decide they want to change it and make it more open - and then they can dual license.
And just to keep it fresh in everyone's mind.

Code
Yeah. I have always been and I am just fine with the code being public domain or whatever you guys want it to be as my opinion.
Text/Images/Expression/Articles - Non Code Portion
If we can figure out weather we agree the CC license should include or not include the ability to be used commercially then we can put this whole deal to rest.
