I think Ponzi scheme might not be the right term here, and to be fair (thanks for reaching out) my goal is not to have you prove anything.
I’ll address one thing - the Twitter audience course. There is no secret/hidden Twitter audience strategy. Post good stuff, engage with others with insights that provide value, don’t post BS. That’s it. That’s the strategy. Anything beyond that is made up stuff. People on Twitter follow those that provide meaningful content that is useful. Short of that, any other automation schemes, follow/unfollow tactics, are just for inflating low quality numbers.
