Hmmm, I signed up for your service. At the end, it was saying there were 500+ people in line ahead of me. I could spam my social media network to get to the front of the line, for a service I had never used. That was a big turn off for me, so I went with other avenues.

The service is in private beta, we are simply not ready to welcome too many users, and I'm sorry for this. Nobody forces you to spam your social media network, you can simply wait :)
