I asked a friend to register and received this list
This doesn’t look very good. 
Hi @Lavender Thanks for the post!
Are you referring the same user? Just checking because they all start with h.
We have some anti-fraud measures in place to limit referrals to genuine new users, it’s possible that you’re getting tripped up on that?
seems like his friend tried accessing the link, but wasn’t successful, so he retried multiple time but it still failed? could be wrong to, I think it needs to be verified
Yes, my friend tried to log in several times (he just couldn’t). It was all just one person.
