YIz,
1) & 2) About the script, its the same as you said. We clone it. We first talk with an user here (
https://bitcointalk.org/index.php?action=profile;u=357952 - you can contact him) to develop the script but since he price was a bit high we decide to clone an ICO site.
3) Of course we use a private domain register, you read our proposal? We could not do it any other way.
4) Really, you know how cloudflare works? There are like 30-50 sites (or more) that use the sames each nameservers.
The website is still the same. you can't deny it. and I do know how CF works, you probably do not because you didn't even start a new account after you finished with Opair.
Yes, we clone it. You can check the source code (using google). YIz, sorry if you were part of Opair, but as we said, your saying have no sense, please contact with CF to know if there are the same account or not (as we said).
CloudFlare is not giving away information. I would have contacted them but it's pointless.
Here you have the answer:
Given the 51 boy name server names and the 50 girl name server names, we have 2,550 unique combinations. This has been more than enough to ensure that the correct DNS records are pushed to our network, even when two people attempt to sign up the same domain.
So there are a more than 500 sites that share the nameserver

. In 2012 (
