As you probably know, on facebook you can remove friends. But can you block those friends after you remove them? What I mean by block, is so they can't see you have a facebook or anything.
it reads
"If you block someone, they will not be able to search for you, see your profile, or contact you on Facebook. Any ties you currently have with a person you block will be broken (friendship connections, relationships, etc)."
so make sure that is really what you want before you block them
