Smilecity is still operating well and here is my latest payment proof. This, my 19th payment is for $20.00 New Zealand dollars and is the minimum you need in your account for a withdrawal. Getting to the minimum $20.00 is not as much of a problem as it used to be. Even though the referral system has been all but removed (Pureprofiles is a much better option if you can direct referrals to their site), There are still many opportunities for surveys and Smilecity still makes a decent supplement to your earnings.
Payments are instant into your PayPal account adn Smilecity is free to join with no strings attached.
