I'm not really much of a big fan of using AI detectors to try to spot AI generated text the best you could do is actually just speculate if the text is AI generated or not because sometimes these AI generators may not give the right results. Nevertheless AI posts seem less interesting to read by people not because they are low quality but because the user posting it just copy pasted it.

There is a some sort of natural urge for reading that comes with a post that was authentically created instead of something that was just created an AI. This is basically just the reason why people ignore AI generated posts.
