The likelyhood that both people went on the internet to describe the same event in roughly the same format with similar specifics of phrasing (eg. “hooked her finger in my Pyrex dish”) in the same order is very low. It’s likely one is a directly based on/inspired by/referencing the other. That’s how plagiarism is detected, and how people behave on the internet for internet points. You’d have to do more digging to figure out which one was first.
Similarly any given story on a forum, especially ones with clean narratives and high contrast characters, is likely just creative writing and not completely true. Some include enough details and evidence to make it plausible, and there’s enough cases of authors owning up to their posts being an outlet for creative writing, so who knows. But with this one, the heightened gender and social outcast fantasy with an antisocial twist, reads like an average misanthropic 4chan poster doing some misogynistic daydreaming. But again who knows. Just applying some healthy skepticism and reasoning.
