“It is absolutely forbidden to suggest someone as a possible employee, business partner or marriage partner if one is aware that:
1. Objectively speaking, it may not be good for the people involved, 0r
2. it does not satisfy the subjecive needs and tastes of both parties.
Not only is it cruel to subject people to situations that are bad for them, it is also wrong to involve the unsuspecting in relationships they would not have wanted had they known the facts.”
“Chofetz Chaim, A Lesson A Day” by Rav Shimon Finkelman and Rav Yitzchak Berkowitz, Day 82.
