(1) the function of the site is like a private club whose secrets are vital to its continued existence,

No one likes chilled speech but there's plenty of examples of legitimate agreements for non-disclosure. Those agreements provide mutual benefit and could be threatened by a ruling in favor of a claimant against NextDoor.
