suggestion: 'rejected' question state or similar

Current behavior

A number of spam questions/posts have been made over time; these don't get approved, so they mostly don't bother anyone just using the web UI.

However, when working with the API these show up by default. You can filter them out by including a published_at__gt filter, but this is not obvious; and you also can't tell (except by looking/guessing from the description etc) the difference between a post that's never to be published vs one that is just WIP.

Expected/desired behavior

• posts have a status that can be set to rejected, or some other field indicating the post is dead
• you can filter out that status/field on the /api/posts API endpoint
