It's strange to see.
I think if someone having low voting Power and he is giving votes of 1% or 10% or what ever, these people shouldn't give upvote instead of low voting. Most of them are Spammers. Who Comments on every post and give a little upvote just for attendance. They mostly don't Read the full Blog.
By the Way, I Hope That Steemit Alexa Rank will also Cover Soon. I Always Hope For Best.
