Interesting.

You could set up high multiplayer, such as 50, and then just vote the comments with your main @ 1% ;)

But since you've already done the work to make all those accounts, I could see why ditching them would be hard thing to do.. but it must take a lot of work to maintain them all.

I'm just glad I discovered this link now, before I was enticed to create an alt for some tribes, because my VP was sitting at 100% for most until I changed the multiplayer. Now maybe I should expect to see more tribe tokens rewarded as a nice side-effect of vote increasing too :D
