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.
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. Rumor has it that certain scammers even pay homeless people to pretend theyre leading a disruptive startup to a bright and radiant future. This fraud is much harder to call out, but at least those guys help homeless people in some way, so heres your silver lining.
If the project is scam, then they really do not publish their personal photos. However, several people can be deceivers in the project, and the rest can be hired personnel who are not aware of the impending deception, here are their photos and can appear on all sites.
Now scammers are more and more inventive and we need to carefully study each new project.
