I assume it's common and understandable to dislike LLM generated content and therefore anything that resembles it regardless of origin. For those who happen to write in a similar way it's a pity.

I've noticed some people on the internet dismiss content just by its length too now. I assume this is because they're not used to the idea of a human producing long form content (as opposed to the short form rewarded by popular feeds). I wrote a post (other forum, other handle) where I included some markdown tables and detailed explanations in an attempt to be thorough and help others answer my question and got accused of having LLM generated it despite writing it myself. Maybe the usage of markdown tables or the length of the post was the issue. Anyway, it's not nice being dismissed as AI slop when no AI was involved. I also don't see how there could ever be a reliable way of identifying origin of digital content such as text on a forum.
