Ask HN: Why my posts are not showing?

Currently they need another user clicking 'vouch', not sure what's up there. Might be related to https://news.ycombinator.com/item?id=24310891 but I'd say it's more a side-effect by algorithm, not deliberate. You can email the moderators (link in the footer). dang is one of the moderators.

From a cursory glance at your comment history, it doesn’t appear that you have been (shadow) banned.

When you say your “posts are not showing up”, are you referring to your comments or your article submissions? If it is the latter, showing up on the front page is more about luck, time of day and a host of other factors than about submission title alone.

There ought to be a FAQ for this.
