As a public relations expert I would suggest one of the problems you are having is one of perception. Since you have named your game after a fraudulent and illegal investment scheme associated with criminals such as Bernie Madoff, people are assuming out of ignorance that your game is similar to the fraudulent activities of other individuals.
I would suggest dropping those references from your site and focusing on the BitConduit brand as the name of the game. You still maintain full disclosure of the rules and payments of course.
Just realized that "Ponzi" is mentioned in the Rules. I've tried to keep the use of the term to unofficial discussions, but not in advertising and webpages. Thanks for the tip.
Which is why the gif in your signature advertising your scheme has Ponzi in it. Right.
