I have always been against automatic vote, if you really build relationships with other users, it implies the reading of their materials and live comments on the subject.
But, I understand that it's hard to find free time for this (every day follow updates of friends and participate in discussions). And auto-vote in a sense is an opportunity to say Hello, to express respect for your relationship. Accordingly, if you withdrew from somebody list you have lost the interest of this person to you. So your actions in this case are absolutely correct.
Sometimes, when you have a lot of your mind. You don't feel like reading a lot on Steem. Hence if your voting power is at 100%, you are 'wasting' potential upvotes.
Hi @michelhenry! Thanks for your visit. I'm not too sure I understand why you're mentioning automatic votes here. I make it a goal to answer as many Steemers as I can personally and give them a manual upvote accordingly.
Great to see you here and I wish you much joy and success!
