Except for Github, every person using it has a copy of the repo and they can restore it. But for Facebook, only Facebook has the copy, and if it's deleted you're done. That's why Facebook is a terrible social platform, at least for social interactions that happen more than in one minute. Older social sites - like forums, etc. - had archives, could be backed up, etc. - but on Facebook, not only you can't properly hold a discussion, but everything you wrote can be removed at any time without any notice.
