I'm bilingual in English and incorrect English... I totally understand.Another of my 'peeves' is those that are self imposed 'grammar' police.
Shucks we all hit the wrong key from time to time and also anybody that is bilingual can easily misspell unintentionally.
Being French/English bilingual I know I often am guilty of inverting some letters and that does not even come close to wrong usage of verb endings nor all the accents used.
Suspect those that are bilingual Spanish/English have the same problem.
