If she is scamming the investing community, it would expose her to legal consequences. That hasn't happened in 20 years. One would think in 20 years the scam and the scammer would be exposed to the legal community and consequences would follow.
One would also think that before investing hundreds of thousands of dollars there would be wise and significant inquiry by the investing group or individual into the company, CEO, and product being developed.
Some may think SMME is a scam but not all arrows point in that direction.
