All new threads go through a screening process (other than for a few long term users). Approval can take anywhere from a few minutes to 12 hours or more depending on when one of us that screens new threads/user profiles has time to log in.
As to the one thread that you have posted (other than this one) it was rejected because the basis of the thread was attempting to get users to contact you so that you can have them contact someone else off site which is just kind of hinkey especially when I have no idea who the third party is or whether they want to be contacted by random strangers from the internet. If nothing else it rather dangerous to be soliciting unknown persons for off site contact since you have no idea who these people are (nor do we ultimately).
