Yes, the bot will need some support to start with and also regular monitoring.
I think if there's a downvote button, it may be used unfairly. Flagging is something users will only do when extremely necessary. I do not see a downvote and only see a flag so all I do is either upvote or not vote at all depending on post quality.
I joined in 3 weeks ago and all I want is to be able to vote generously and to get fair reward for the value I add. I hope Steemit becomes better as a platform. Thank you for your efforts.
