I checked out one project with six team members and not a single linkedin link on the profile pictures worked. I reached out to them and asked what's wrong, so they added two functioning links and removed some of the links of the other profiles. Then I asked whether i could speak in the telegram group to the CTO, just a single question. Or whether they could do an AMA on Youtube. That is like 6 weeks ago and they haven't done it, yet of course claim to be the next big thing. But that happens all the time with projects, on a very frequent basis.
I don't know if you can talk with high ranking guys in the project if you don't have anything good to offer to their project since mostly the one who talk for them is there community managers but you can seek the answers with your questions to their live AMA sessions so even if they are there showing there real faces still we need to be careful since scammers are now upgrading to gather more money by showing their identities to gather trust to the community they created. So for thinking about investing on this better invest only what you can afford to lose since that is the golden rule in investing.
