How about new rules for user that can voted must be having more than 20-30 Post,and have been registered for more than 8 month?,or conitec need to pick a jury/make jury team of their choices,and also user vote getting accountable but with this weight :

Jury Vote Weight : 60%
Forum User Vote Weight : 40%
Total Decision : 100%

By these it would be more preventing cheating and more fair result.If we continue like these,heck i would just make tetris/pacman clone and make a vote spam bot to gain good vote,In the end of the year i can have 5 'free' commercial edition .
