this filter isn't used at all on normal search results pages
It would explain a lot if it was though, a real lot. Mainly that almost no UGC shows up after basic. As I said, i think it's at about BASIC+.3 if it is being used.
If what Rish3 supposes is true it's a pretty terrible way to analyse content. At any rate, it does appear (as mentioned) to simply favour long bombastic phrases, and rewards empty pages with 'advanced' (that empty page did have some Slovakian in the side bar). It is a very immature technology from what resultant data (thanks @lucy24) we can see.
I hope you're right, something like this should not be in a complex algorithm that affects so many people's time, effort and livelihoods.
