It could @mibangs. If you did make it, I would give more customizability instead of all your followers. Here's the problem. The more you upvote, the more SP you use up... So unless you have all of the SP in the world this could really hurt you. I would suggest something such as picking a random user from your followers and upvoting their latest post on a daily basis or something such as that... rather than upvoting every post by every user.
