Was I just censored by Digg?

After the recent discussion about companies offering bribes to Diggers, I thought it would be interesting to run a poll asking if it's time for the top users to be paid by the social news site itself. I was interested to hear the views of the wider Digg community so I 'dugg' the post too. Predictably the story quickly gathered momentum (Digg's users enjoy stories about Digg), and after approximately 90 Diggs and 40 comments it had hit the front page.

Then seconds later it vanished!

(The odd thing is it still shows up in my profile as the only story I've submitted that has ever made it to the homepage.)

Now I know I've previously described Digg as a broken democracy, but I've never thought of it as a dictatorship. So what had just happened?

It turns out that my submission had been buried, but by who?
This is how the Digg FAQs describes the 'Bury Story' feature:

Stories can also be removed by users with the 'Bury Story' feature within digg. Once a story receives enough 'buries' it is automatically removed from the digg Upcoming or Popular sections. The number of reports required to bury is based on a sliding scale that takes several factors into consideration (such as number of diggs, reports, time of day, topic submitted to, etc.).

Based on this, it could simply be that Digg's algorithm had just kicked into action; though it's hard to understand why a story that's been dugg 90 times in a few hours and has over 40 comments, can hit the front page before it gets buried.

Alternatively, did I witness Digg's moderators in action?

Update: The DuggTrends graph shows the point at which the story hit the front page and then got buried. Tony Hung has some interesting thoughts on what he calls the 'Bury Brigade'.
