WoW!!! Thanks for the warning!!!! So You think that the project is a scam because some of our Team members use artificial photos as they do not want to expand their faces.
Just think about that "maybe" some of them has a serious reason to do that....for example....may work for a bank or they are in government. Anyway this is your opinion but not the truth.
Thanks
If they have issues with revealing their identity, then they should have mention that, or even better, not use any pictures at all. That is perfectly legit decision by the way, not to reveal real identity at all. Good example is Satoshi, but what he never did is using some fake photo to try fool people.
But, you wanted to appear more legit and attract people, so you used stock/fake photos for your teams members, and that is not honest behavior.
They often times use black and white photos or color overlay like in this case to make finding original image sources harder.
Yeah, they do use some tricks like that, or distort the image a bit, hoping that reverse image search won't discover true origin of those photos. Situation is getting even more complicated now, with advanced tools for creating artificial photos that are harder to detect.
