Boycotting voting would be a good way to track down voting. However, this would only be useful if the tothegames site were receptive to such 'proof'. Possibly a good idea to support an argument, but the web site already has all of the raw data, and could get much more accurate values directly.
Perhaps to counter down voting, those with dynamic IPs could vote once a day (then there would be no need to coordinate efforts), possibly at different times during the day (one day in the morning, the next in the afternoon).
