Isn't upvoting a bot comment same waste of delegators money as offering vote rounds with high ROI? What if delegators are using Steemit only to gain profit by renting SP and not making any posts? Then they will also loose when idle bot will not have any post to upvote.

I've just checked 5 random bots with 0,01 SBD minimum vote. All of them were uncapped and did from 40 to 570% ROI in their last round. 90% of bidders will choose bots with possible ROI over bots with no ROI. How will this reflect to delegators profits?

I have concerns as Hive account@slimwhale delegator. This is not bold criticism :)
