I can remember very well that when I was a newbie, some links that I post can be removed like this. Like Jawhead999 said, this will no longer happen to you as you rank up on this forum.
@Asta124, you have gotten the answer to the question that you asked, it would be better if you lock this topic to avoid other people to be posting the same thing that has already been answered.
To lock a topic, go down this thread, you will see lock topic at the left side. Lock it.
Edit:
You can see that I attached 2 links, and only the one from CNBC was removed which is strange. If newbies are prohibited from using certain links, please give me the details anyone.
It happens to new users only. Not all links are affected.
