Just wanted to let you know that you are
not being singled out for attention by the moderators. We don't care about your politics or conspiracy theories, honest.
Everyone already knows that John Dillinger shot JFK, in any case. :-)
You've got it backwards, BTW--posts do not normally have to be approved before being published. Posts that trip our automated spam warnings do get queued for moderator action, however.
Due to the huge amounts of spam we were receiving--to the point where real posts were being buried--we've had to institute some heavy-duty filtering. (At one point I was personally deleting upwards of 100 spam posts/day...) I didn't implement the filter, so I don't know what the exact criteria are, but a post containing a long URL is quite likely to get held for moderation, especially if it contains one or more words on the "likely spam" list.
Good luck figuring out your hierarchical display issue.
cheers,
