I remember back in 1998, when learning about being #critical to sources.
Some of the tips on detecting unauthentic #sources (today known as 'fake news') was to look for typos, grammatical errors, and inconsistencies in the article.
These days, only #satire sites are typo-free, use proper grammar, and are internally consistent within an article.
Another tip was to look for the articles sources; those are rare in news articles these days!
I'll leave it to you to figure out the take-away here.
