Referred HiveOnboard-created profile

I've just created a custom subdomain for my Hive account@hiveonboard referrer URL as follows: http://hive.eaposztrof.com and love to use it, BUT:

1. sometime just doesn't load my data to the Referrer box
2. there is a scary rule, like: phone number is required
3. but when someone will step back because of it, the username already occupied, profile is generated, but impossible to sign in with the generated private keys
