IMO it's because Neucoin likes to lock people into an investment, so they can't say anything negative without knowing they are hurting their own chances for success. Anyone who signed up for the growth account has shutup and smile for the next 3 months, and that's how the Neucoin team likes it.

That's also why they won't update the neucoin-qt client. They want everyone using the growth account for the lock in.

It reminds me of the multi level marketing/pyramid scams that go around from time to time. Once you buy into it, if you say anything about how you're losing money, failing to get other people involved, etc., then you are just hurting your chances to get others signed up underneath you. So everyone involved has this weird fake plastic smile, while they all sell their souls on the inside.
