Have you ever see an ICO going on and see the team listed on their site have no social media link like twitter linkedin etc? Sometimes yeah that some people don't use social media that much but you still curious who tf this guy and why I trust him with my hard earned money for some dream project. So you guys check the team image by search the image in google or Yandex or any other services and found out they just take other people image from google, what you guys will do?
If you just wonder how many scam ICO with a fake team out there, the answer is to many to handle.
You guys can go to scam accusation board here
https://bitcointalk.org/index.php?board=83.0 and see how many reports made for a fake team running an ICO. And that only ICO we proved to be fake and I'm sure there lot more ICO going on with the fake team, you just can reverse the image edit the color or just picture random person on the street and put it in your website to make it though.
So just another advice from me, don't put your money to some random project without proper search about the team and the project itself, knowledge is a power. Just because your friend or family invest that doesn't mean you have to invest too.
Even with a real photo of them, they even still can scam you and get your money later.
There must be a concrete proof about the existence of the company, otherwise it can be fabricated.
Faking the team just one of the method they use, other things are important too.
