As I don’t have accounts on those websites that leaked. Take Last.fm I have never used that site, my email address isn’t in use on that site either by me or someone else so how can my email and password be exposed from a leak?How are you so sure your password has not been leaked?
Another one Heroes of Newerth: the multiplayer online battle arena game. I never sighed up. My email hasn’t been used in an account by someone else so again why is it listed as exposed?
QuinStreet is another one I have never used and there is no account. Like I said I don't trust the haveibeenpwnd website.
