If this is the case we need to know which girl not to contact by WhatsApp. Some wgs do prefer contact via WhatsApp. Can’t just blanket ban WhatsApp.
To quote blackpool rock on page 1:
So she didn't refer to watsapp on her AW profile and you tracked her down, as far as i'm concerned and i'm sure everyone but you watsapp is social media so it's no wonder she has blocked you.
Why take the risk of some girl blocking you when u can text her instead?
Your point of some girls prefer watsapp, i have never ever seen that on a profile ever.
