Yes, snubbing women works.
However, this strategy will not work just by itself. This may be obvious, but it often goes unsaid. She actually needs some other reason to be into you (looks, confidence) besides the fact that you sometimes snub her.
Most women who say snubbing doesn't work don't understand that distinction in the question, but, for women, if a guy you ARE ALREADY INTERESTED IN, snubs you, you women will want to know why. Women have huge egos, accustomed as they often are to the attention of men. The snub creates a mini-crisis of self-confidence in the woman. In order to recover their sense of self, they must resolve the slight. Women mistake the emotional crisis they feel at having been snubbed for a deeper attraction, or even love, and thus will only feel satisfied once they are sure they have commanded the male's attention. This often means having sex with him.
The very same principle operates if you date one of your ex-girlfriends friends. The ex-girlfriend feels slighted and her sense of self is threatened. In order to recover her ego, she must reestablish her attractiveness through conquest. This means having sex with you (the ex-boyfriend) again. In her mind, she has proven she is more attractive than your current girlfriend (who is dating you because she is competing with your ex-girlfriend), and she has proven that you still find her attractive.
As long as you understand this simple principle that governs all female behavior, you will have many successful sexual relations.
And women, remember, these adventures are conquests for the woman as well as the man. The concept of gender has two sides; women are not merely innocent victims.
Peace.
