Did you ask anyone to vote for it? Did you announce the post on Twitter or anywhere else?

You might want to email the mods to ask them.

I announced on twitter and posted to reddit. Is this prohibited?

I don't know if it's forbidden or not, but it can trigger some of the HN mechanisms that detect voting rings.

I'd email the site (the address is in the guidelines) and ask them about it.

The article looks interesting, and it's a shame to see it sink so quickly.

I've already emailed there, won't make a difference probably anyway. I hate this HN tricky rating, one my post got dumped from top 5 cause there were too many comments!

Reddit kind of saves the day :)
