This is already the case. If you post in the "tutorial" section, your post will be reviewed. You will immediately earn your credits, but your post will remain unvisible until it has been read by a moderator. Then, the moderator will appreciate your work, and of course will give you extra credits. But if the moderator decides that your post is purely spam or if he finds out that your post has been plagerized from somewhere else (including from your own website) you may have a very bad experience.
