While ntro/raw/cbi are falsely claiming that posting on the forums is a service, the main reason for using forums is finding new websites for making money online to pay domain renewal fees.
The domain investor has noticed that google is not listing new money making websites in the search results
It is mainly listing websites of banias, brahmins and other part time bloggers who have not updated their website for 3-4 years
For example google is listing websites with top 100 lists of writing websites
These websites claim that they are paying $50-$100 per article
Yet in reality these websites will not approve most of articles submitted, wasting the time of the person writing the article.
In comparison using forums helps because members are posting the latest information of websites which actually pay.
