It's interesting that this post is falling off the front page so quickly. At the time of writing it has 537 points and is 8 hours old. There are many above it with much fewer points, that are much older (eg. 127 points, 12 hours). It makes me wonder if YC intentionally penalizes posts like these, because ideas like these make it harder for their portfolio companies to hire employees.
I believe it penalizes articles that have a large number of comments relative to votes.
I'm also suspicious, although most suspect as sibling comment to yours suggests, that it's likely something automated rather than malicious. Perhaps there's too few comments?
