Yes, this is all handled automatically by me. When you write a comment I do not automatically upvote that. But you can send a memo with the link to the comment for an upvote.
I work like a battery for steem power. Your sp is stored and charging up all the time and can be used to upvote posts. As soon as the capacity is full I will vote on someone else and give you a weekly payment for your votes. You can even go a little into debt and upvote when you are empty!
