I don't really get it. Maybe xb360 really does have a 1 million kills achievement, so when I edited an image of another achievement to make it 1 million kills that became similar to the actual one?

Or was it the image of GW, which I found with a google search on facebook, which famously does not allow their members to copyright photos posted there?

This is what I hate about DA's mods. When they remove something they'll give an excuse but they won't give a reason.
