You're making an assumption that everything placed on social media has been placed there either by or with the owner's consent. That is not always true. You're assuming that the "Terms of Service" are in line with copyright law - which also isn't always true. You're also ignoring a number of other privacy laws that may apply to images and posts on social media. Reposting anything has its risks, especially if you do it in a manner that reflects negatively on a person or organization. And FYI, a signed waiver has never prevented a person from suing the entity providing the waiver.
