The object of the Poison Pill is to conflate real conspiracy with made up crazy stuff in order to dismiss criticism, confuse people searching for information, and muddy the waters.
The idea is to trick a social movement into taking the pill, which will discredit itself by perpetuating incorrect disinformation along with real information.
As an example, here is a video, allegedly about chemtrails
It has all the classical signs of a poison pill disinfo operation. “Ron Johnson” (STF news puts out a lot of disinfo, probable government psy ops troll) in the video claims that a digital negative image is chemtrails in “night vision” and that cell phone towers can destroy a city.
