63 C-10 Carolina Fleetside
I may have had the same problem that you had couple of days ago. My name was shown as the writer of a post that I hadn't made. The message count by my name was only 2 or 3. It was in a forum that is not shown in the Forum List. Looks like it may have been a forum that the monitors created to temporily hold messages by new members - possibly to capture spammers.
I can't find the post now.
That's interesting. There is no forum like you describe. New posters' posts are marked (NA) for not approved, and only Administrators and Moderators can see them until they are approved.
As for the reason for 63 C-10 Carolina Fleetside's name being on all those topics, I don't know the answer to that yet.
