See: ProPublica as a great example (source: https://www.propublica.org), along with the ICIJ (behind the Pandora Papers, source: https://www.icij.org/category/investigations/) and other investigative reporting outlets.

The Investigations sections of The Washington Post (source: https://www.washingtonpost.com/national/investigations/), The New York Times, and investigations by local newspapers are often very good, though occasionally they can be of lower quality.

I agree with vast majority of your comment, though to nitpick a bit, a curated social media feed can show this content (e.g. ProPublica's Facebook/YouTube/Twitter, and through using carefully curated Twitter lists). Also, from a cynical perspective, I know of some people doing it for the thrill, the fame, and the power to hold otherwise-powerful people accountable instead of for higher ideals, though I don't mind so long as the results are still ethically produced and rightfully empowering to the disadvantaged.
