Once again, someone (a Facebook “frined”) posts something on my Facebook timeline that seems pointless, an ad for sunglasses. I don’t see the point. Sometime back, I unfriended someone (female) who posted fictitious tags of me in sexually explicit pictures on my timelines, claiming I had been “there”. Don’t really see the point.
I do wonder if there could be a legal or TOS liability if someone posted something illegal on one’s timeline (c.p. or terror promotion) and the account owner didn’t see it. I get emails from notifications, but if I were in a remote area off the grid, I could miss it.
I presume Section 230 would protect me from defamation claims for someone else’s posts (as it does from comments, although I moderate comments on blogs). On copyright infringement, technically I have to be an “agent” for safe harbor to apply. And for some specific illegal items (like terror threats) there is no downstream liability protection.
