Does a user hold copyright on content that he posts on soup.io? Which rights does a user give to soup.io by posting content? Does a user automatically give other users the right to repost his content without prior asking?

Your disclaimer says that a user who posts any content must either hold the copyright of this content or must have the explicit permission of the copyright holder. How do you expect a user to do this when he just wants to share e.g. a random video from YouTube or a great comic?

How do you ensure that users don't include feeds in their soup.io-feed whose copyright (or explicit permission of the owner) they don't have?

Do you obey to RDF-license-tags or links with rel="license" so that e.g. content that is licensed under a CreativeCommons - share-alike license is shared with proper licensing?
