All you have to do is set up the parameters for what the conditions are for cheating (i.e. Looking at someone else's test for an answer, getting up from your seat maybe, most taijutsu skills probably, many ninjutsu probably - could you use a fireball jutsu in a room without being caught, etc. Also I said the chunnin exam would be twice a month, cause in the anime it comes twice a year. You are still able to do missions and learn jutsu as a genin. This also makes it so people strive for something, for two weeks they work on their skills and practice and then join others for a team. Speaking of which, would you join up with other users as part of a team for the chunnin exams or just add computer players? Honestly I think it you should be able to do either. Obviously if you join with other users you have a greater advantage to getting through the exams, but then you have other people that may not think the same way... pros and cons.
I'll agree that voting is probably the best way to do it, maybe to have a simple voting building/booth where you can see the missions that each shinobi has completed (i.e. 35 C-rank, 22 B-rank, 15 A-rank, 7 S-rank, etc.). How long they have been on online?
I don't think it will take that long, I think most should be able to handle a five minute genin test which is the tutorial at the beginning. The "written test" could even be on movement right after you go through basics with the instructor so everyone should pass that one. The other tests gives the users an opportunity to see what their character can do at the beginning. If you put no stats into genjutsu, your character will not be able to release genjutsu, that makes sure the user knows that they cannot even release genjutsu and at the beginning they can decide if they are ok with that. Same with ninjutsu and taijutsu.
