The usual best way to get in touch with dang (or another mod) is to email hn@ycombinator.com. Likely to get a better answer via email, or perhaps he'll comment here if you call attention to it that way.

If something like this really happened, this is pretty disturbing. The _pecl account that now owns that comment was created on the same day the comment was posted, has 1 karma, and has not posted anything else.

Edit: just emailed hn@; hopefully someone there will follow up on this.
