In a testimony to how socially unacceptable it is for a woman to complement a man, there is an OP in the sub Letgirlshavefun about how forbidden it is for a woman to complement a man. That sub is about women doing things socially forbidden to women, and there is a post about women complementing a man. That's right, women actually feel they cannot complement men even if they want to.

I know in this sub I cannot post a link directly to that OP. But if you want to find it, just look for an OP about complementing men.
