Reddit or (a very small number of) youtubers are pretty much the only sources of truthful and good-faith product reviews. Almost all of my recent purchases are due to recommendations by hobbyist subreddits like r/mechanicalkeyboards, r/photography, r/bifl, etc.
Google automated ranking, using totally random pagerank algos, which was their downfall. Reddit and youtube, in general, rely on crowdsourced ranking, which is harder to game (not impossible).
