Yep, I am using an autovoter bc sometimes I don't have the time to use all my 10 100% votes (if you are having more HP you will mostly vote more with less %) but it's kind of wrong that autovotes get a bigger piece of the cake than manual votes
And the reverse auction thing to find good posts and promote it is kind of broken if autovotes dominate the whole chain.
So yeah change to linear rewards.
