Question regarding problem I am having with facebook...

Wait. So.
He blocked you, and you’re trying to add him?
If that’s the case, then he has to unblock you.

You can do this by clicking Remove next to their name from the bottom of the Privacy Settings page. Please note that this will not automatically add them to your friends list. Instead, you will need to search for them and send them a friend request if you wish to become friends.

@rangerr well yeah he did block me. And yes, I know he has to unblock me. My question is how….

If it’s a new account I don’t see how you’re still blocked…

My response explained how. From your brother’s FB account… To get to the privacy settings page, click on “Settings” in the upper right corner, then select “Privacy Settings” from the drop down menu. Scroll down, and there will be a list of blocked users at the bottom of the page. Click on remove next to your name. You’ll be unblocked.

FB can block by email addresses, so any new account with that email address associated with it will be blocked.

@Anonymous_Observer well actually, he blocked my new account. He still has my old one, but I don’t use it ever.

@juwhite1 oh why thank you! I understand now….thank you for all your help :)

You’re welcome.

For future reference, you can find all this information on Facebook under “help.”
