If someone on Facebook says something blatantly slanderous / libelous, you can't sue anybody. Ditto with Youtube, etc. etc. So if you're going to say disinformation, its best to do it on Facebook. You can sue the person who made the defamatory statements...That's basic defamation law. If you mean that you can't sue Facebook, that's due to section 230 of the Communications Decency Act. If you mean that it's difficult to sue people making slanderous statements on Facebook, that's true, but it's not impossible and plenty of people have succeeded in suing people who slandered them on Facebook.
