Let me first explain you what is treated as spam.
Spam is something which you convey your message to the user which is not at all interested in. More info here Spam (electronic) - Wikipedia, the free encyclopedia
But if you post about clixsense on forums which deal with earning money online then it may not be treated as spam unless the forum owner has permitted you to do so. Be sure you post on forums which are related to earning money online and read the rules of forum before posting them.
In my opinion unless you are posting on related forums of your topic and following the rules of the forum it is not treated as spam.
