I had some questions PM'd to me about what the hunter bots were attacking and thought I would post the information to everyone.
The "H" series bots are patrolling the perimeter and are searching for targets that have 4 or more coins. Keep in mind the general is also worth .96 coins.
The "T" and "F" series bots are moving towards coin areas but will attack targets on their way that have more than 6 coins. Once in a coin area, they will destruct on the highest value non moving target that has more than 3.5 coins.
This evening I have turned off the "Q" series bots which were probably the biggest ones to gripe about on the board. These bots were seeking anything above .96 coins. So they would attack any general that came near them as they patrolled the perimeter. You will see these bots on the board still, but they will not do anything.
I also disabled some of the other H,T,F bots for about a 35% reduction. Again these bots will be on the board but not moving anymore.
