I do it a lot even in early days I use to guage a women's interest level and once I see her putting her best foot forward I take her. I don't ignore her messages though. I just do reach out unless they do. Some women especially those who these stuffs can quickly tell what you are trying to do and won't fall it rather they won't take you seriously and they will take you through a lot of sh*t tests. So be prepared... if you don't have the balls don't do because it might back fire at you. Your ability to know the kind of girl you are dealing ( low self esteem or high self esteem) is very crucial. The high esteem will walk away quickly especially is their interest level for you is low.
