Facebook Policy Change Hoax: Your Posts Are Not Becoming Public
Turns out according to snopes.com and komando.com that this is NOT TRUE and is a HOAX! A quick Google search of UCC 1-308-1,1 308-103 and the Rome Statute shows that neither one of these "codes and statutes" have anything to do with social media.
They are dealing with commercial transactions and international crimes. So you're wasting your time sharing that posts because Facebook will not be making your posts public. Use your Google my friends!
