Not knowing whether you actually gave the advice you're blaming them for not taking isn't professional, it instead comes across as bitter.
i think they are extremely personal and actually very distinct from professional criticisms.
Personal and professional are not mutually exclusive.
If I criticize your code, that is a professional criticism.
If I criticize your code and say it reflects your consistent carelessness and stupidity, it is also personal.
If I say you fabricated something, then that is a personal criticism, it alleges an ethical violation. In a professional context, it's also a professional criticism (every profession has some ethical standards).
