If the project is a scam, it would be really silly of its team to show their true identities. In most cases, they just find some pics online and use them as the images of their Chief Financial Officers or advisors, as was seen in Empire Card who used a picture of French actress Sabine de Poncins, little known outside of France, as the portrait of their proud imaginary CEO Patricia Harrison. There have even been reports of Ryan Gosling working for a project as a designer under a completely different name.
For this case it is rather easy to detect if they are using a photo of a famous person, we just need to check it with a tool to check the authenticity of the photo and if the photo is fake it will appear several photos similar to that but with different identities.
Some scammers are, however, way more intricate. They know its quite easy to reveal a fake pic so they just hire people to pose as their CEOs, CFOs, and so forth.
This is indeed the most difficult and most investors are fooled by this trick, but if you examine it carefully then other alternatives you can learn what they really do. If they provide the new innovations and clear solutions, then our doubts can be reduced because of this. Another way you can also verify their office address, if you live outside the country, you can search and check it through google street view.
