You just linked to a template that has articles describing the various methods of misinformation and disinformation that exist, but present it in such a way as to say "HURRDURR WIKIPEDIA IS FAKE AND THIS IS PROOF." While very real consequences flow from Wikipedia being, as it calls itself, "the free encyclopedia that anyone can edit," the best way to fight them is to change the respective articles and have screenshots and archives ready to go if someone maliciously reverts the article to a less factual version.
