Your site is a job search site so the fact that someone has an account means they have been job hunting. This is not like Stack Overflow or Hackernews that you seem to like comparing the profiles to. StackOverflow may have job search functionality but it started as primarily something not related to a job search so my having an account there doesn't mean I have been job hunting.
Your SO account was also never private, didn't contain "test scores" for job skills, and was never a repository of sensitive information about you that you only allowed them to have because you trusted them to keep it private.
I've seen some epic CEO fuckups but this one is special.
