The real problem is, at the end of the day, you can't prove or disprove these are ever 'real' or not - and before anyone mentions repeatablity, repeatability is NOT indicative of authenticity! I can get any LLM to provide a repeatable answer for an infinite number of things (what day comes after Monday? I bet it will repeatably answer Tuesday!)
It's like the simulation theory - it can't be proven or disproven, so just stop trying.
At this point I can at least understand why these stupid prompt conspiracy theory things thrive so well on social media though.
