Then there's the possibility that someone enjoys intentionally pretending to be clueless as a means of trolling and further enjoys that it disrupts people's instinct to provide guidance to misguided rationalists.
That would be incredibly difficult on the moderators. Thankfully, being smart enough to think of that and dumb enough to be a troll isn't a very plausible interval for human intellect.

This is my attempt to codify the informal rules I've been working by.
I'll leave this post up for a bit, but strongly suspect that it will have to be deleted not too long thereafter. I haven't been particularly encouraged to try responding to comments, either. Nonetheless, if there's something I missed, let me know.
