Re: How can I find out who's server admin?

@soemlyrussian servers ban because admins are dumber than a rock.
i looked on your bf4db profile and you have orange stats (meaning you're good above the standard with that gun) so what the admin don't know that orange means good stats and not CHEATING stats if your k/d ratio and/or HSKR aren't above the roof. Orange stats are typically misinterpreted as DMG hack (it happened to me as well while i don't cheat but i'm a decent Q3 / UT instagib player so used to aim for HS) and got banned from a similar russian server (what a joke) because i was too good with DMG rifles....
Orange stats are usually above the standard when you play hardcore mode (read 1 bullet makes MORE dmg than one on a standard server).

Replying to your question: there's no chance to find out. You can ask a friend to join that server and ask for an admin

give XP and mark it solved if so
see you on the battlefield
