I just created this post asking for input on three different down-vote bots. I've made some major changes, both to the voting power strategy and to the previously indiscriminate part of the vote bot upvote attenuation. Most notably the added use of the age of the post being upvotes prompted by grumpycat's recent downvoting activity where he distinguishes between early bot aided " promotional" use of self upvotes and late bot aided "money making" self upvotes. While grumpycat uses a surrogate (the voting bot used allowing late usage) my bot will use the actual post age itself, so reducing the false positive rate to zero. Please have a look at the whole blog post to understand my project. I'm sure you will see the good these bots will do, and maybe you could even add a bot idea of yourself.
