Ask HN: Am I flagged by HN moderator?

Fogscreek's post and mine are submitted at about the same time: http://news.ycombinator.com/item?id=3001173 http://news.ycombinator.com/item?id=3001182

I've gained 8 votes, and they have 5. They are 22 on the front page, I am 51 on the second page. My post was on the front page for about 30 minutes, until it suddenly disappeared.

I am wondering if I've done anything wrong, and if next time I can avoid getting moderated (if I was indeed flagged).

I believe I am trying to contribute to the community on good faith. So I would appreciate it if somebody can let me know if there are topics or rhetorics I should avoid.

The source code for the ranking algorithm should be visible to anyone who can read news.arc source code. I haven't read the source code myself, but I get the impression that comments to threads matter for ranking as well as upvotes. Flags (which wouldn't be visible) also matter for ranking.
