Nameserver bug

I found a bug when you go to add a new domain to your account and it says change it to:
ns1.rf.gd
ns2.rf.gd
Then if you add a domain which hasn’t changed it’s name servers to that yet you get a message saying that we didn’t find your website and you need to change your nameservers to:
ns1.byet.org
ns2.byet.org
ns3.byet.org
and so on…
So I just wan’t this to be fixed because I got confused by this and didn’t know which one to change it to and other new people might get confused as well. I think the rf.gd bit differs depending on what subdomain you use.

You can use ns1.rf.gd and ns2.rf.gd or ns1-5.byet.org. Or both. It doesn’t matter, they all work.
