So your 40% decrease in reports of interactions means what exactly? You have had a decrease in the reports of possible or substantiated cheating? Were those reports coming from players or your automated system?
Would you also be saying that you have had a substantial increase in "inactive" provinces based on your comment about cheaters letting their provinces go inactive?
How long are the devs allowing a province to be inactive now before it becomes abandoned and the monarch can delete it or use it for an invite?
Because based strictly off numbers, your system hasn't done anything. So ROFLMAO is pretty valid based purely on numbers alone.
