While you're right about these lists being careful to mention if there's even a hint of switching, some of these lists also contain stories where there's no penetration at all (because the lister knows the story won't bother the fans of bottom!so-and-so either way). And I'm not always sure if it's made clear when a fic is included on these lists because it's "non-offensive" rather than really "top!person"

Did that make sense? So I'm just imagining that if you went by these lists that depending on how the lister chose to interpret it that you would over-represent one dynamic over another.

Unless I'm wrong about that, which I might be :)
