I didn't receive coins yet. I was the one who joined the list very early. Waiting for the word from the dev. I think I was not too late to be in first 1000.
I think the process is still ongoing,the dev hasn't announce that the free peep coin has stopped so wait for the announcement I'm sure he'll consider the those who first sign up to this give up away ...
May be, but I fail to receive anything, I would have wasted my one of valuable tweets to peep. I don't think it happen.
