AAQ: Even by Shidduchim there are halachos that prohibit sharing certain information under certain circumstances (i.e. if the person you share it with might share that sensitive information unnecessarily with other third-parties who are unentitled to know that information.)
FW: Halachicly it is prohibited to read books of kefira. Halacha also requires that we not share loshon hora (even though it is true information), motzi shem ra or rechilas and moderators are required to refuse to publish such comments.
