#3 needs to be #1 in my opinion. I think upvote bots are not good in the long term in spite of the benefits for those that use them in the short term. They retard the growth and full potential of what Steem.

Maybe an option to filter out posts with paid votes would be good for people. If don't come to Steem for ads, I come here for outstanding content. With bid bots in place, sometimes the best content is difficult to find.
