I posted some concerns I had earlier on, I'd be very wary of using this mod until some of the ways of "gaming the system" are resolved (for example, if you have a coordinated group of trolls, they could easily cause mayhem, or if someone created a lot of multiple accounts it would be REALLY easy to abuse)
Here is a mod for another forum software which shall remain unnamed, this mod does the same thing, but has some features which make it harder to game (on first glance). Perhaps grab some of the ideas in there?

In addition to those features, some other things that might help stop abuse:
--Have "seed users" - assign permissions to a certain group who are the only ones who can use this mod. As these seed users disseminate points, or rate posts as +, the users who are being rated become able to use the tool (so only those who are trusted can use it, and it spreads through trusted users first, blocking the trolls before they have a chance to game the system)
--Require a certain number of posts before someone can use the system to stop lots of multiple accounts from trashing your forum. If a user has to post 10 times before they are allowed to use the feature, then they are already being rated by other users and are therefore identified as good/bad early on.
--Ensure mod posts can never be hidden (again to stop troll abuse)
I really look forward to this mod.
