not credible in what way? The company does not exist? They are not trying to mine their own land? They did not register in Hong Kong? What's fake about it? Instead of making empty blanket statements why not say what you mean.
Interesting none of the rampers are saying anything about what the article contained. Instead they are trying to divert the topic by saying it's not credible just because they had to pay for newspaper space. Well duh, taking up a whole page would not be free. it seems obvious to me they are trying to reach a large number of people quickly. If it was written by a journalist the rampers would argue it was a fake article planted by SMM.
