It's people who muddy the waters when it comes to people asking legitimate questions about certain aspects of life being fucked up or kiked. For example, when someone mentions that vaccines can cause problems, you get a whole heap of these "muddy the waters" fuckwits who will hijack that and say "You have to remove toxins from your body with (insert kooky food/method here)". It's the same as the "space is fake" guys, it's to muddy the waters on discussions of things outside of Earth. It's all to delegitimise legitimate discussion and to make those people seem as kooky as the nutjob types.
