I don't know how long you mean by 'old' but this nickname was used by an old player from the 2005-2006 era that has sadly believed to have passed away now.

Though, sadly because I'm a huge cunt and can't help myself you are now banned for 1 month.
After you come back (if you decide to!) please do not use the name Polonez and choose another nickname.
Dearest and kindest regards,
Powodzenia!
