The Polish version of the opt-out text which shows in the opt-out iframe includes this string: "Kliknij tutaj dla opt wejciowych." There is no such word in Polish as "opt" and the phrase "opt wejciowych" is meaningless. A better phrase would be "Kliknij tutaj by wczy ponownie." And for the opt-out "Kliknij tutaj by ponownie wyczy."
Also, the phrase "analityk statystyk" is grammatically ropey, it should either say "analityk statystyczn" or "analiz statystyk", but not what it says at the moment. :)
