I just wish the bot would stop telling me that the images Ive uploaded that dont have a known source (and were released under Sharealike 1.0 which doesnt require a source) are candidates for deletion.
Creative Commons Attribution-ShareAlike 1.0 *requires* attribution. In fact, all the Creative Commons licenses require attribution.
I didn't say Attribution-ShareAlike 1.0, I said Sharealike 1.0.
Right, the (disused) CC-SA doesn't have the full attribution requirements of CC-BY-SA.
Nevertheless, I think some indication of source is, if not legally required, then a really good idea, and I think this is true even for works explicitly released into the public domain (as opposed to, say, trivial ones ineligible for copyright, or stuff with obviously expired copyright).
If nothing else, we'd want some sort of attempt to establish that it really was released into the public domain (or under CC-SA).
