Thanks! It is a balancing act that can be achieved, but most people seem to be either staunchly anti or pro self-voting and need to think carefully about the long-term consequences of both stances.

Just banning self-voting will merely shift that activity into voting-rings and sock-puppet accounts, which then require going back to some similar rules as proposed above. So that means we end up with two new rules rather than just one.

I keep going back to one key finding in game theory research: non-optimal behaviour for a system cannot be wholly eradicated but can be minimized. The reason it cannot be eradicated is that it will reappear in another form.

I think the returns on investment are still pretty good compared to others, if one is treating this as an investment.
