Should we let people get away with crime or hurting others? if you don't want that to happen then there should be real world consequences for what someone post on social media. This is because if someone post about commiting a crime they should be punished for attempting or planning of said crime. Another reason this needs to happen is because if someone were to use social media to cyberbully someone there should be consequences for the danger they put that person in.
Depending on what they post, whether it provocative, rude, or inappropriate. It doesn't matter if you delete the post, what you put on social media/the internet is on their forever.
