Not the OP, but in my mind I want a system that rewards members who are improving the health(mental and physical) of the largest possible group of other humans. The anti axis of this would be producing pain in the smallest set of other humans possible.
The way to punish behaviors that are scoring worse on the above would be to reduce the total number of connections possible to other humans. You would need a recovery sensor to catch run away cascading punishments and isolate for rehab.
So you find someone who has healthy relationships and you empower them. You someone with unhealthy relationships and you isolate them and rehab.
Someone who can maintain large n umbers of healthy relationships is a leader.
