Getting accepted into a campaign is not akin to winning a no-fee raffle but conditional on being the most suitable forum member DarkStar_ is looking for. Other people applied, and yet FomA's alts were chosen over them, clearly indicating who was a better fit for the campaign.
Given the number of applicants and no lack of good ones, DarkStar_ is probably throwing a dart at the shortlist, but that's not the point. If FOMA didn't break the rules then someone else would have taken his place and earned that money. Therefore FOMA breaking the rules did negatively affect whoever was next on DS's shortlist, even we accept the rationalization that FOMA didn't steal from DS/CM. The fact that we can't name the affected users in this situation doesn't mean they don't exist.
