Since the Ilum exploit, and their utter failure to take any action against those involved (despite their blog to the contrary), the precedent is set that exploiting and/or cheating is allowed (or at least tolerated).
If they were serious about eliminating cheating, they would have taken action sufficient to deter people from exploiting in the future.
The next time something comes up, you can bet almost everyone will exploit it. There is no incentive not to.
