That's a terrible disclaimer. You can't just disclaim your way out of statutory liability.
There's probably nothing to worry about with re-publishing an already public fact, but the cases where errors are made e.g "I'd hate to be my boss" filled under "People who hate their boss", the casual reader may be confused (some might say mislead).
The solution is just to keep people informed, so your disclaimer may say something like: "the information on this site is automatically collected from public posts to Facebook. Posts are classified automatically, and as such our classification of their sentiment may be inaccurate."
Also, just in case one of the Facebook posts says something defamatory, hate speech, etc. you can gently remind people that you didn't write, edit, or approve of the content so "are not responsible for the content of messages".
