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.
I have never seen photos in profiles similar to the homeless).I think you're exaggerating too much.The main criterion is an account that was not created before the start of ICO.As a rule, people with experience come to the project, so this experience should be confirmed (I mean Linkedin).
