To be fair, the FCC ignored the automatically generated comments and focused on comments that were unique, detailed, and relevant. The actual scandal should be what they did with those comments: those that supported rolling back the NN rules were accepted as fact, those opposed (i.e. those in favor of NN regulation) were dismissed as "not compelling." I know this because my comment was among those dismissed as "not compelling," including specific sections that dealt strictly with the factual errors in Ajit Pai's proposal. The only reason they bothered citing my comment (and numerous others by actual technical experts who took the time to comment) was to avoid being sued for ignoring the public comments (they are legally required to consider public comments when making a decision).
It is also worth mentioning that Ajit Pai differed from his predecessor Tom Wheeler. Wheeler had intended to introduce rules that allowed various NN violations but changed course in response to public comments and went with the stronger regulations. Pai never cared what the public had to say and made that very clear in his public statements, where he basically said that the only thing that would change his mind would be comments concerning the FCC's legal authority (not that there was any serious dispute about that legal authority).
