I have wrestled with the Help feature for an hour.
My laptop is close to being thrown into the back yard.
Story is I blocked quite a few American colleagues as I didn’t need to see a heap of their political views (not personal- you wouldn’t need to know mine either).
However, I need to unblock a couple. All I can find is help to unblocking applications. I want to know how to see these folks posts again.
Are you still friends with them? Hover over the news feed button on the left side and a little pencil icon will pop up. Click it and it will give you you the option of removing people from your block list.
BTW, it sounds like what you did was hide (or what they now call unsubscribe from) them. When you block someone it unfriends them and makes them totally non-existent to you. It may have been why you had trouble finding it in the help section.
Hover pointed to the left of “News Feed” (in the column on the left). When a small symbol appears, click on it and choose “Edit Settings” from the menu that pops up.
That opens a window with a list of hidden friends. Remove (click on the “x” beside their name) anyone you want back in your news feed. Click “Save”. Bob’s yer uncle.
