Its not even a question of banishment, its simply a case of these forums are a pretty unique platform online. If you find yourself here to share knowledge and increase your own with no thought of selling, self promotion, gaining a following, making a name or promotion of products. Well then you will find this place is amazing and populated by amazing helpful people who have had more success than thirty of me and practice as much if not more humility.
If however you are here to gain in a tangible and immediate way, here to attract enquiries and directly increase or promote your business interests. You will find it populated by ruthless skeptics and cold receptions, we are not offering solutions or selling plans we are literally helping each other in the most honest sense. It is what makes this place special, unique and why we are so passionate about it.
So really thats all you need to consider, as that will dictate how welcome you feel here.
