Imagine this senario:
The license requires attribution, and that remixes be shared.
Someone alters artwork from opengameart.org, they then decide to post it back on opengameart.org, but they decide to violate the licence by not giving credit to the original creator. Does opengameart.org allow the artwork to continue being hosted (they are aware of the infraction, but unaware of which one is the original to attribute to) in violation of one clause in the license, or does opengameart.org remove the work from the site thus enabling the remixer/submitter to violate both clauses?
what does opengameart.org do?

We'll remove the entry if they fail to attribute properly.
You have a misconception about the requirement that "remixes be shared". I assume you're talking about CC-BY-SA. Let's say I create a derivative work of a CC-BY-SA work. If I only keep it on my hard drive and never distribute it, I'm not in violation of CC-BY-SA.
Share-Alike means that if I actually do distribute this new work, I must give attribution and must use the CC-BY-SA license. When we remove the art from OpenGameArt isn't no longer being distributed (here at least).
If you are referring to a specific item post here on OGA please inform us which one so we can take correct action. If you already told someone on the team, I apologize if it hasn't been taken care of already. We strive to do the right thing.
