With how long it's been on the front page, how controversial it is, and the fact that it was posted earlier and that post _was_ flagged... I would be willing to bet a moderator has somehow disabled the ability for this post specifically to be actually flagged and is simply ignoring those that click the flag button.
I'm sure that seems conspiratorial but the guy writing the post effectively "cuts the checks" for the moderation staff here.
