In a perfect world, community members would cooperate to rate each other's contribution and derive a fair compensation. In the real world, algorithms must be designed in such a manner that they are resistant to intentional manipulation for profit.

(LOL) Nice!

He is an actor?
exactly.
I learned from this. @dantheman is very important here. I am told he did not like my post. He wrote this too but I do not want him to dislike me here. He wrote this paper too. I am not mad about that.
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.
