I recently set up a public OpenPGP key server in the US that synchronizes with the predominant global key pool. I now have a server on my hands containing gigabytes of user-generated content (e.g. names, comments, the keys themselves, etc.).
I assume based on the commonplace of such systems that I am legally permitted to distribute that content, as that is, after all, the point of a key server.
But I'm not comfortable just making that assumption. Is there a definitive explanation of the content's copyright status, or at least a similar situation involving other user-generated content to which I can make reasonable comparisons?
I've skimmed the web interfaces of various key servers and have found nothing to the effect of a terms of service document. Normally with this kind of question I'd ask the primary source or distributor of the data, but as this is a decentralized dataset I'm not sure where to go. I expect that other key server operators are in the same position as myself.
