Your reputation says it all. No one will believe you as there are so many scam investment are rising everyday. This is not the right place to promote scam investment.
In fact, his reputation should not matter much here. Everyone should be aware that such "projects" are created only to steal peoples money.
In my opinion, if someone is not even the author of this scam, then by promoting something like that he is fully aware of what he is doing and should be punished for it. .. And that punish, should be much more than just a negative opinion on the forum ..
