I don't ask for concret legal support, but have a general legal question about the CC.
Suppose i am the provider of a wiki and i made sure that only registered users can add content. On every "post" all users are forced to agree to "Your Content is CCed".
Now, let's assume that others are using this content to redistribute it or to distribute a - again CCed - derived work.
No problem so far.
Now it turns out that some of my wiki contributors
a) post content which is not their own
b) deny the "declaration of intention"
What about the consequences?
Who is liable for compensation?
a: The individual who posted at first? (What if i do not log user-content connection?) Or the "provider"? Any of the redistributors?
b: Me, the provider? Any of the redistributors?
Sure, this may depend on the juristication. But this is IMO a big issue for any individual which wants to use/provide CCed content:
Am i save to do so, or do i have to face legal problems?
