There are some good bots, like the ones PAL/MSP teams made.. and the Originalcontent bot..... there's also minnowpond bot but that one still at early stages... its vote won't be a big help.
There's also cheetah bot which searches the internet for similar content to all steemit posts, this can be either good or bad bot but in my opinion it's a good.
hmm thats actually an interesting point!
