Not everyone here are reading the whitepaper or checking the website completely. That's why controlling someone posting a promotional project will be a good idea. Suggesting that Newbies will not allow to post a project without a consent of higher ranks. In that way it will help reduce people who is posting a scam. Its a bit too harsh but it will be good suggestions. If higher ranks will post the project then people will accept it and check atleast or give it a try.
