Someone I know has a child, now in their 30's, who has married someone who has a YouTube Channel. This child's spouse is posting videos slandering the child's family, but without mentioning names, but saying "the sister," "sister's husband", and the child's "Mother". They are claiming these videos are a "reality" video, even though what they are saying is not true. Can they be held liable for this as the statement they make are not true and can be proven not true with witness'? There is much more to this story, but I'm just trying to discover if these videos can legally be taken down as it's tearing the Mother apart. I am keeping this vague as the 'child's' spouse tracks everything. Thanks in advance for the help!
