Blocking prevents people from communicating directly with you on Facebook, and you from communicating with them, but those results aren’t permanent. Facebook devotes an entire section to managing your blocked users. In this section, you can see a full list of those you blocked, and unblock them if you wish, with only a couple of clicks. Once you unblock those users, however, you have to friend them again to regain your prior status as “friends.” If certain users blocked you in return, you will not find them or be able to send a request for friendship.
