After reanalyzing PAC logs I come to a conclusion that it was not mahrozulamin`.
Players Hawk and Sports will be held responsible for impersonating Jellyfish, mahrozulamin`, =Zubi= as well as some others.
From now on the subnet 182.181.*.* is completely blocked due to high number of failed logins, impersonation attempts and multi-accounting, but we are likely to add few known regulars to the whitelist (after looking into their ban history, that is).
Mahrozulamin` has been unbanned.
