What I think is that, if anyone makes an undeserving post, still he will get upvotes through this automated system.
What I feel is that using steemvoter tool is against the spirit of steemit. In steem we upvote those posts which we see and feel that they deserve an upvote. I also stopped using steemvoter because this problem.
The better way to find great posts is to follow good authors.
If we can add a review system in this "Steemvoter Exchange" then we can improve it.
All of these are my personal opinions, but still you guyz are doing a great job. Keep supporting minnows. ;)
