"Unapproved" in postings now?

What? My posts are suddenly in moderation? I just posted an answer to a thread and was greeted with a green outline saying "unapproved". Whom have I offended to deserve that?

Yea, you offended some backend heuristic AI that wants to take a few potshots before going all-out "kill all humans!" on us.
