I have observed that some users exaggerate their language proficiency and even some professional teachers don't know what a native language means.
A Ukranian girl can have Ukrainian and Russian as a mother tongue, but native in English and Spanish?
In my opinion "native" is not a proficiency above the C2 level. Even I have seen native speakers with pathetic language proficiency. Native means you are born in that language but it is possible that you did not learn the language properly.
Come on guys change your language proficiency in your profiles and be realistic!
