Anything post-2022, and probably post-2020, is suspect on Reddit because it became abundantly clear how steerable it was and how easy to generate sales as long as you didn't do anything too "suspicious". Current 'ad guides' tell advertisers not to link things because just saying the name reads as more authentic.

Before that it was legitimately people discussing, e.g., the best flashlight for x-y-z purposes. But a decent amount of old stuff has been gutted by people deleting their posts/accounts.
