faggots help!

Such a thing, my grandmother opened the Internet, and unfortunately went to the wrong place. Full package:
- Tiktoks with a country of disinformation from phimotic incels.
- The first channel, which is like on TV only worse.
And so on and so forth. To my attempts to explain that you should not believe any bullshit without checking, she issued an ultimatum - "give me, vnuchek, an algorithm (How is it, to search and check the dat'ы enti, vnuchek)
So...Does anyone have an adequate article on the principles of checking and confirming data on the Internet, simple enough to understand and not really stupid? Of course, I am now looking for something similar, or rather I will even write it myself, but I will not say that I am very attentive and tem pache, competent in the matter of verification.
