This is a response from a mod that I got from when I asked about mod preview of posts:
I'm a moderator here and posts do not need to be approved. However, your first post was a strange, weird thing with a bunch of odd characters and the words "University of Greenwich" and that was it. One of my fellow moderators wished it into the cornfield never to be seen again.
We get a godawful amount of spam and such here at the SDMB and moderator policy is to disappear them as quickly as possible. It's also policy to ban such spammer with no notice. You appear to have avoided this fate so whichever mod did it must have decided you didn't fit that profile.
In any case, welcome to the Straight Dope Message Board. I hope you'll enjoy your stay here and find many threads in which you can contribute.
