Generally speaking I search Reddit for genuine looking negative reviews not the glowing ones. I'm looking at Reddit to steer me away from obviously bad choices.
Basically, shilling has become so pervasive that positive reviews are automatically untrustworthy regardless of source or apparent trustworthiness. It wouldn't even surprise me to find that companies are generating fake negative review content without ever endorsing their own products, but it's at least a tiny bit harder to fake genuine modes of failure to report on.
This entire thread dumps on Orbi Wifi devices and praises Eero. Maybe Orbi is inferior to Eeero, but the one-sidedness of the discussion is a bit unsettling.
The top comment was created by a poster who almost exclusively posts on the /r/eero subreddit over the span of one year. Many of their comments are specifically in praise of Eero devices.
It's one sided but that's a lot of shills if you think they're shills. Shills with 10-year-old accounts and active posting history that continues to this day. No, I'm pretty sure at least some of them must be authentic.
Of course, this only hilights that user reviews are hit and miss. It's not so uncommon for something to work well at start but then you discover problems later on.
On technology specifically I tend to view these types of threads more through the lens of tribalism than shilling. Like, I don't have reason to believe Lenovo or HP is paying people to whine about Apple online, I'm willing to believe people will do that all on their own.
