I think more factors need to be taken into account. Number of Views. Number of external links. Number of comments. Quality and length of comments. Time Stamp of upvotes. This could weed out auto-voting.Content is currently judged by the popularity of the author or the money of the readers, not the quality of the content. This means Steemit is a popularity contest!
Agree... And auto-voting is actually counter-productive in determining quality content.
