Finding team members whether if they were real or not doesn't guarantee the entire credibility of the project itself. Plagiarims, on the other hand, is very essential point, if you spotted it, you should avoid the project as soon as possible, much better if you'll remind other participants about it.
If we talk about whether there is plagiarism of white paper in the project or not, then one rule says a lot. If there is plagiarism, what conclusions can be drawn about the project itself? They are unable to write the document on their own?
There are many investigations on this forum that have been conducted with allegations of plagiarism. And on those projects, there is something like a “stigma”, and they are marked with flags. But what is most surprising is that the developers themselves do not understand their mistake, and over time, after rewriting their document, they demand that the forum acknowledge the honesty of their intentions.
There are some time that finding about the photo if real or not does not help. I hope what happens on 2017 will not repeat, some scammers CEO are not scared to show their faces on social media or even blockchain conferences personally, and some did even get a selfie with well-known crypto individuals and use it to promote their scam projects. My point is, the photo listed on their website is real but they have hidden motives, I never heard one of them go to jail. But finding the photo if real or not will surely minimize any possible financial damages.
If the project is a scam, then there will be no photos of real developers. They are all afraid to show their identity, hiding behind the fact that anonymity must exist in crypto.
These are either random people who do not suspect that someone is using their photo. Or there may be some really famous people in cryptography who also don't know about the project. And also the photo that the computer generates. Such photos look very natural, an unknowing person can believe in the reality of the photo.
