So a lot of people get on forums to chat with friends, some get on because they are bored, and others get on to promote. Unfortunately most of the people that get on forums are only trying to promote spam aka "stuff nobody wants!". The whole reason no-one can insert links into their posts is because of all these spammers that have ruined it for us. Regardless of how good and useful a product you have you will only get banned from forums if you try and promote yourself. So how do we make money posting on forums? Well believe it or not the better the writer you are the more you will get paid. If a forum is filled with topics that are un-educational and boring people will go somewhere else for help or to chat. Some owners of forums will actually pay people who are good at writing to post in their forum just so people will come and read it. On the flip side the better you write the more interested people will be in your product because they will see you are a normal person not just someone who only knows how to say "FOR YOU EVERYTHING HALF PRICE. I MAKE YOU BIG DEAL TODAY ONLY FOR YOU!" So a word to the wise is this: Only post useful content on forums that people need. If you are promoting a product that is useful and good people will want it and you won't have to trick them into buying it.
