My apologies for wasting the limited time and attention of the admins.
My guess: The domain is too similar to HN itself, or the fact it's a lower-value aggregator regurgitating content from other sources, got the article killed.
The posts are [Dead], not a regex issue, nor is it an issue with administration.
From the FAQ:
>What does [dead] mean?
>The post was killed by software, user flags, or moderators.
>Dead posts aren't displayed by default, but you can see them all by turning on 'showdead' in your profile.
>If you see a [dead] post that shouldn't be dead, you can vouch for it. Click on its timestamp to go to its page, then click 'vouch' at the top. When enough users do this, the post is restored. There's a small karma threshold before vouch links appear.
As for the other one and your recent comments, it's a failure to follow the guidelines[0].
