I just replied to 2 different posts.  For one of them, my reply posted immediately.  For the other, nothing.  I don't know if it's waiting for approval, or if I need to repost.

But what isn't known is how posts are queued and if they all go to the same moderator or different ones.

even when you are, some posts will go into random moderation.  That used to happen to me and I think it happens to others.

There were some keywords that seem to now be banned.  Specifically, the name of a certain ad site that is named after the greek god of love.  

But sometimes a totally benign post will be randomly selected for moderation as well.
