I can definitely agree that bots are bad in some ways. However, Steemit is for humans and humans can be stupid/greedy. Stupids (and the bad kind of bots) will vote on greedy's posts, even when they are stolen from someone else. I think Cheetah is a great bot for pointing out potential plagiarism (no harm done when the source is cited in the article). And flagging? I loved flagging when someone stole my post and pretended it was their own. I'm pretty sure most people would feel this way.
