According to the Steemhunt moderator's post (answer 2a) from a few days ago, any Steem account with rep over 60 has voting power of 3.

That might change, of course ;-)
it's great if hey could add more power to the higher reputation accounts. It really gives a sense of worth to the people who have put a lot of investment into the eco-system. It's not easy to reach 70+ reputation at all.
Account based voting is always vulnerable to sibyl attacks(multiple accounts) and some people like berniesanders own 50+ accounts. If you use bidbots you can reach 60 reputation without loosing much money. It will only take few hundred dollars at best.
I hope @steemhunt would change the ABV after SMTs and use something like HUNT Power with slightly non-linear rewards (n^1.1 to n^1.3)
This is the exact argument of some critics of the current system. That it will basically degenerate into a battle for votes from as many accounts as possible. Today's announcement confirms the big effort in banning v4v attempts.
Im glad you mentioned "investment" because i think one's SP is correlated with his investment in steem, hence its value in any system. Will keep you posted as this plays out 🙂
At the current stage V4V can be taken care of. But when the platform grow big enough for something like a million Daily Active Accounts, these ABV system are unsustainable. But there is a lot of time to improve. So things will be OK.
