I never knew that this forum existed. The whole internet has become so filled with advertising since all the new companies and eg google etc that they promise people money for the ads and try to get in sites like curezone.
There is one group, so far they have used about 10 different names and they all have links in it. I don't think they are a small group or that person is just smart.
At this point they start answering questions or they ask questions like they are legit and then later the links come back.
I have never understood that site you are talking about, it seems just commercial and not in the line of curezone.
Yahoo forums are often filled with ads too.
There is no easy answer.
