It takes ten times longer to point out all of the things wrong with an LLM-generated post than it does to generate it. This is a losing battle and a miserable way to spend one's time. It would be preferable to simply not see zero-effort generated content drowning out real content, but because the zero-effort generated content outnumbers real content 100:1, it requires a high degree of active moderation intervention that sadly isn't present.
