I am still one that believes in the human perception.
Yes, machines are good and all, spun content detection is good and all BUT all these start to matter IF shit content get $$$$$$. And when they do, as it was case with msgivings, a lot of eyes are on her. A lot of eyes = a lot of spidey senses that something is amiss.
Pay attention to who's trending and on what - the worst content, the most money, the most dubious should be asked to provide proof.
That this is not the norm now, only shows where Steemit main interest lays...in which case, all this machine detection is useless when a society chooses itself to be blind to the corruption.
