If 95% of the post is used by bots, there are no comments and the person used 200-300$ on the post, and I read it and see myself there is no value it brings to Steem, I will feel comfortable with my DV.
If the user uses 200-300$ on a post, gets 100 comments, lots of non bot upvotes, and I think the post is trash, well I won't DV that because it is obv bringing value to Steem. At the end of the day I am an investor, and if you feel the need to blow your post to the top of trending using the inflation pool allocation, then I will use my stake to make sure you are not abusing what really is a glitch in the Steem system atm.
