It should probably say this somewhere new sign ups can see like the FAQ perhaps so they're not left in the dark and actually understand why it takes the time that it does. I'll quote someone I highly admire, "it is the way it is because people are shit", couldn't be more true.
The wait time is what it is, leaving people unknowingly in the dark while the problem gets worse and worse is just a silly thing to do.
It is in the FAQ.
Yes, but it should be in a "welcome, please be patient while we review your application manually" email XP
I can imagine setting up a system of emails, 1 per week, explaining the whole concept of cryptocurrencies, Steemit's place within that context, how to make a superb first post, a few posts to read while waiting, etc...
Something to keep people interested in Steemit even if they can't participate immediately.
