What if we associate points in contest for catching cheaters just like hacks.
What scenario I am suggesting is after the contest is over a window will be their (say 24 hrs) in which one can claim which user has cheated along with proofs. Then moderators will agree/disagree with that claim and points will be given to one who claimed (like successful hack). I believe this is a spontaneous setup bcz more the number of cheating activity, easier will be to catch one. So this will constantly keep check on cheating activity.
Advantages
Catching cheaters will be more streamlined.
People who have lost significant rating in contest will put lots of time and effort to report such incidents. That will guarantee success to reduce cheating.
The setup of this will be very similar to hacks — not much work would be required from development point of view.
Disadvantages
- Someone needs to validate if the claim was correct, for that the contest organisers need to allocate some members for this task. (Since it is time consuming process some benefits should be alocated to promote this work(kind of sh*twork)).
PS — Don't know whom to tag, please someone do that in comments.
