Well, as a member of the modding community since 2005/ joined ppm in 2009 I certainly know how the community rules work. Being the community rule protector in Chinese community I actually need EA official opinion - so I can have more confidence defending decent mods like MO from unwanted hands. Simple banning/deleting would cause much unnecessary quarrel and flame wars.
As I said, the very assets you're trying to protect should probably technically not even exist in the proprietary SHP / voxel formats they are in... I doubt there's even a basis for real copyright discussions here.
And, honestly, I doubt EA cares what mod makers do beyond the scope of "they're violating our EULA but we're allowing it for the sake of the fan base." All the rest is internal squabbles, as my linked topic from 2009 shows quite clearly. It's already in rule-broken territory; I don't think anything legal can help you there.
The EA people here are community managers and tech support people, though... I doubt they can give legal advice on such matters.
