The researchers argue that the ends justify the unethical means because they believe their research is meaningful. I believe their experiment is flawed and lacks rigor. The delta metric is weak, they fail to control for bot-bot contamination, and the lack of statistical significance between generic and personalize models goes unquestioned. (Regarding that last point, not only were participants non-consenting, the researchers breached their privacy by building a personal profile on users based on their Reddit history and profiles.) Their research is not novel and shows weak correlations compared to prior art, namely https://arxiv.org/abs/1602.01103 https://arxiv.org/abs/1602.01103
