I've talked to Vaqnoku on Mumble, who is representing his friend (KirillP).
The situation is the following:
He invited his friend, who is new to minecraft all together, to the server. Upon trying to log in it says he is banned. I checked the ban history and he has no records, so I assume they are using an IP that was blocked during the spam attacks.
So he needs a higher up to fix the situation.
