The reason for some projects why they are not hiding their identities is first they are confident with their projects will become successful thats why they invite people to fasten together and then eventually it end up to a disaster which will be consider scam. Come to think of it, why will you show your face if you know from the beginning youre just deceiving people, of course you will easily identify and put in jail. Next is when other video projects are just used by the scammers, but the real video and project is real and you didnt carefully notice that it is just a fraudulent one (many sites are doing that). So I guess the best thing that we can do is to stick to pioneer and establish projects which already collected many trust to the customers.
