You don't even choose who to give your script, do you? This is a 15-year old girl. Have you read through her post in the first place?

You upvote posts because you think that the post is of good quality, not because the person who posted it is your follower.

Just "Follow" For "Free Potential Votes" For Your Future Posts

If this is your definition of giving upvote then you are defeating the purpose of upholding quality posts. You are very good at playing safe for the "potential votes" with no guarantee even if they follow you. How sure are you that you will remember this person and come back to upvote her future post when you did not even follow her? I checked and she's not on your followed list.
