I know my ex was an EXFJ based on the Jungian description of the Fe-dominant type. But I took several MBTI tests based on what I know of her and how she would have answered and I got ENFP every single time. EXFJ 7's in particular are never going to test ESFJ on any MBTI test. Ever.
Plus FB is very much EFJ and ISJ domain for the most part. They're around. They just hang in different circles.
