Frustrated new user... this could improve

I spent a couple of hours replying to a pose where someone asked for a security review of their hashing algorithm, which I am happy to do, but after all that work, WTF? Where is my post.

Is there a secretive moderation policy that only applies to new users, or was my post actually lost? My new thread also has not shown up. I did not read that my actions here don't take effect in the same day that I post. If that is the case, please make it clear when folks sign up.

Of course, this will be my third post, which I assume will also not show up... I hit the Submit New Thread button, which from my point of view simply doesn't work.

I just recreated my original post, with a lot less detail since I didn't trust this system, and once again it dissapeared. Why does posting here work, but posting replies in the cryptography section seems to discard my posts?

While posting you were shown a message that some post MUST be reviewed by the Site Staff.

The message isn't up long, but most people do see it.

You have since posted enough to not be in the MUST be reviewed by the Site Staff..... ALL of you hidden posts have been approved.

I think its because a moderator need to approve it. Ive noticed the same when im posting
