Go to your homepage, click the tab that says "Personal Details" (under your profile picture). It might make you login again, but then you'll be taken to the details page. On the left there's a column...you'll see "Blocked users" as one of the choices. Click it, and you can navigate from there.
I'm new to this so I'm sorry if I'm not giving you the answer you are looking for but I wanted to try & help! I think you go up to the Home tab & then scroll down to Privacy, which helps protect your page & information that you my only want certain people to see!
