If they blocked you that might explain why you can't see them from your page. When they block you, they can no longer see your personal page - i do not know if this also prevents them from seeing fan or business pages associated with your account.
There are NO trackers or profile-visiting notifications on Facebook.
Sorry, I meant NO trackers. If you go to his page, he will not know.
The only way to get unblocked is to ask that person to unblock you. You can create a new account, but wouldn't they just block you again?
