Yeah I would love it if I could put in some guardrails for this type of stuff, eg never use Grokipedia or Reddit as authoritative sources (I currently put that in my personalization prompt).
Why not Reddit? Of course, it's far from a paragon of truth, and it's getting more manipulated and overtaken by bots by the minute, but adding "reddit" to my search queries (in search engines, that is) had always been my go-to for finding answers and threads by actual people, especially if we're talking about technical advice or getting an opinion on something. It's like finding forum threads on something I'm interested in.
