People who post frequently on these forums with links to their own websites are not spending this much time for free. It may appear that their web pages are "ad free", but everytime you click on one of the links within the web sites, you may be directed to a website which IS selling products and which DOES contain advertising. Since the person who posted here managed to get you to those websites, even though it took two steps, they collect a fee. It's essentially payment for referral.
So again, someone may say their sending a message to everyone about a miracle cure with hundreds of testimonials "out of the kindness of their heart", but there is an ulterior motive. No one would put in that much time building websites and then going out to solicit "hits" through CureZone.
Look at some of the posts that I'm referring to, and look at how many hits each one of those posts gets. Most of the readers will click on the link, and then a percentage of those will unsuspectedly click on multiple links once they've gotten to the "gateway" web page. Each of those clicks can be generating revenue.
In addition, a lot of readers here love drama. So, the more drama, the better for the web site creator, because they will get even more hits on CureZone.
Yes, there may be some merit to the suggested "cures", but we all know that there is no one right answer. The person posting is off the hook though, because all of the proper FDA disclaimers are in place and the poster is pointing to secondary references who are actually on the hook for the efficacy of the suggested remedy.
Moderators have a tough time putting a stop to this because the poster praises CureZone, and even includes links back to CureZone on the "gateway" website. So the website can also be a "gateway" to CureZone. This can make the moderators at CureZone more tolerant of the behavior.
This is a known way of making money on the internet, but I can't say that everyone who has such a system established, is necessarily guilty of this type of deception.
