I believe displaying info about the team doesn`t make the project a auto non-scam for several reasons.
First of all, how can you be sure that these people are real? Photoshop is still a thing, as well as fake accounts on LinkedIn.
Then, what`re gonna do after they run away with your money? Trace those people and lodge a lawsuit? See point above, nothing prevents people of the project from being fake personalities.
ICO teams are in perfectly safe position here: we can do nothing to them, the only action available is to invest or not. We`re basically entrusting them with our money with no safety-trigger.
