Keevil/Currah will be known as scammers forever. They will find it nearly impossible to steal investors money with new scams. The gravy train is over, it's time to get a real job.
You can be sure investors who lost money on these scams will follow these conmen and expose them whereever they go and in whatever new scam they try.
I doubt Currah could get elected as dog catcher. Their presence at any company will be a certain indicator of a scam.
