se my reply in the post itself.. I sincerely doubt his upvote was anything more than an automated upvote of some certain amount of comments from steemcleaners. It seems very unlikely to me that he read the post or the comment (as i suspect he would have picked up on the metaphor).
EDIT TO ADD -- actually, looking at steem cleaners history, i was probably wrong he probably did see and upvbote the comment... but the broader point still stands.
