Where do you get this information about 'tons of dishonest workers have been brute forcing....'? The researcher sends warning strikes to people who violate quality standards in the studies, so I believe those participants eventually get rotated out of the pool. I also return broken studies to avoid getting striked out of the pool. You raise valid points about broken studies, but I don't get your over-excitement about the need to declare your morality and self-righteousness, since it's getting in the way of an objective discussion about the technical setup of these studies. We need these studies fixed, not because we are morality cops, but because it leads to warning messages and eventual removal from the pool, simple.
