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 it’s 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 they’re 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 here’s your silver lining.
