Hey, @metama, for steem to work, for STEEM to have value, there has to be some kind of link between posts, how much effort went into them and how much rewards they generate. Nobody can tell you exactly what a philosophical question like his is worth, but a vast majority of people would agree that $70+ is way too much.
See value of money is rooted in social conventions.
So promote your posts with bots if you wish, but try to respect the value system of the steem community. Try to keep some kind of proportion. If you need a "ballpark estimate", had you promoted your question to $5 or even $10, I think nobody would have bothered to object.
"Everything in moderation", keep that in mind
