The simplest way to spread the word is via word of mouth. When you get yourself out of debt and back into the black you become a shining example to all those people you influence with your new found courage and actions.
You radiate confidence and people ask how you have done it and then you will spread the word in a way the listener will take time to understand, so he/she can further teach it. If you look and live the part you are the part not faking it to make it but acting it to be it. You not only spread the word by teaching but by others talking about you. You become a matter of fact, not some guy on a website.
No need for social media and other shortcuts they will just increase the misunderstanding of the movement. Also social media is controlled for quality by agencies like GCHQ, your ads could easily be labelled spam. Lets build a network of trusted friends who actually help each other in real terms. Meeting, talking and solving.
Best wishes for all
