I've used these account creators (mostly Steemworld) and created quite a few accounts for people. It's good to have at least 5 to 10 tokens in the bank for when people need it, if there were a shortage, I would just ask for some invites. The fact that it costs 1 to 3 Steem is rather insulting and should only be there to prevent spammy abuse but when someone legitimately wants an account it should be free.
