I really enjoy being able to download CAWs and copying their full attires with custom logos onto another CAW, the last console game I played the logos weren't copied over. It's handy for when someone uploads a great attire for example, but it only has one and you want to fill the 2nd slot with a great attire from another caw, or replace it.
So hopefully that never gets reverted in favor of stopping thiefs. What I think would be a nice solution if it's possible is to have anything that someone created themself always carry some sort of tag. So you uploaded a logo, used that logo on your caw, uploaded that caw... then someone downloads it and copies it over to their own CAW, an exact replice, to upload it themself, well that CAW will somehow tag back to the original creator so that any downloads this copy gets will count as a download to the original creator and people can see the "original creator" as well as the creator of the copy.
And that could work for anything, like shows having an arena someone else made, it will indicate that it uses parts made from someone else (in this case, the arena) and you can look at that original creator's page too. I don't know if something like this is possible, but I think as long as the tiered uploading system exists, it sounds like a good compromise to me.
