I've been to numerous websites discussing the truth about space and the earth, and it seems one thing is consistent for many of them: NASA proponents. If truth has been demonstrated these NASA proponents:
(1) Start flooding the sites/threads with chaff so as to negate what has been said
(2) Facilitate ad hominem arguments to consume time and negate the efforts of those speaking truth
(3) Promote cognitive dissonance to frustrate and deter those seeking truth
It is so consistent and persistent that the directive they are working from is observable by pattern of operation alone. It is apparent such agents are here promulgating this agenda as well.
I concur with what you are saying 100%. You said it perfectly. I’ve experienced every aspect of what you have described. I can’t really improve on your OP, but I would like to add a few comments based on my experiences in posting responses to NASA related YouTube videos.
I’ve noticed that there are a handful of specific YouTube characters who appear to be patrolling NASA related videos. I will usually post a flurry of responses over the course of a week or so, then I'll get tired of it, and I'll stop posting. Then, a few months later, I will get the urge again to post some more comments, and I find that the same characters are still there patrolling the videos, never missing a beat, as if it’s their job. By scrolling through the comments, it can be determined that the same characters have been patrolling these NASA videos for literally YEARS.
One of their main tactics is to get people to waste as much time as possible. They will keep responding with asinine questions/challenges, deliberately twisting words to frustrate people. Like you say, "the directive they are working from is observable by pattern of operation alone."
