If they don't show in your fan/business page's banned list, I'm going to say that they aren't blocked/banned from the page. You probably blocked them from your personal page.
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.
