I had some people on autoupvote on Streemian also. The same thing made me remove everyone and stick to manual upvoting. My upvotes are probably not worth much presentl but I'm sure that they would be of help to someone. If one person decides to post several times a day, there is nothing wrong with it. The decision to either upvote all the works or select a few good ones and upvote them lies in with you.
