this happens all the time on reddit and it definitely worries me a bit. People post what is, for all I know, complete fiction and people seemingly take it as fact. Point out that it could be made up and watch those downvotes fly...
It's almost a creative writing contest in some threads. The problem is that just enough situations are verifiable that it blurs into the well written fictional accounts. I spend time on r/BestOfLegalAdvice sub and I have no doubt that upwards of ~25% of posts are fake.
