You should take some case issues to @sherlockholmes

Here is another link to add to yours https://steemit.com/steemit/@o1o1o1o/bots-gone-wild it outlines some issues with the Cheetah bot that could be fixed

I have seen Seraph's work on a post of mine as well https://steemit.com/goodnews/@cryplectibles/good-news-everybody-new-futurama-here-no-seriously-in-this-post-right-now-steemit-friendly

Good luck on any pursuit to help get these bots fixed to be something working for all users of Steemit including the ones that haven't joined the site yet.
