On one level, FJ doesn't need any 'technical' means for enforcing attribution. But they do need to expend the manpower to investigate reports of misattributed content, and to actually correct them (either changing the attribution or removal). I mean, this mechanism should exist anyways for dealing with 'internal' attribution disputes (some user reuploads another user's actual original content from FJ). Other user generated content sites (like deviantArt) have proecsses and mechanisms set up for this.
