Some of the links you quoted were automatically removed because they were indicated as suspicious links.
That's a Newbie restriction, and should be lifted by now.
It should not be restricted if it is not a short link.
I see other restrictions for newbies, including the following:
-snip-
- Newbies cannot upload their own avatars.
- You must have made one post in order to send PMs.
- You need 10 posts to put a link in your signature.
