I think it should be of a concern if you ask me, I think there should be names to the teams/organisers of the alt-coin/project and not only name a very comprehensive data bio of them also, so one can see their profile, experience, knowledge, previous success and failures.
Also hiding names sounds shady/fishy, I have heard of alt-coins manipulating there pre-sale to use it to advertise for their main sales, you have to search more on that project.
