I highly doubt everyone gets moderated. But I'm not included with that group. I was just moderated the other day but then I will go awhile before it happens again.
I've found that if I submit my reply too quickly relative to the amount of content it has (like if I hit "reply", paste a whole macro, and submit with little typing, I get moderated. Once I used alt+26 to make a right-arrow and got moderated then as well. →
It's happening to me also on about half my replies, and in fact yesterday it happened when I edited one of the FAQ blog posts. It started late last week.
So the moderator was moderated while talking about moderation and now he needs to moderate his moderated post so that he can talk more about moderation without being moderated.
