Art submission CC-BY 3.0 w/ Attr. Instr. requiring more

Art submission CC-BY 3.0 w/ Attr. Instr. requiring more

So I noticed some of the considerate art submissions by http://opengameart.org/users/downdate of late and I also noticed the Attribution Instructions, such as the one in http://opengameart.org/content/sorry-you-lost-stamp, make the CC-BY 3.0 license seem a little shaky.

This part "You don't need your permission but we want to keep track of use" makes sense and seems like a considerate thing to do, it is the "in case of licensing problems and the like" that follows it that makes me a little uneasy.

Any thoughts out there on this? Does this compete with the CC-BY license? Is it in OGA spirit?

Lastly, should we verify that downdate is authorized to post on behalf of that project since we have to ask them if we can use their art?

 

Thank you for your time,
