Any idea where do they get the numbers and how do they do it? WhatsApp marketing
I guess we need to write to TRAI about this, need more regulations! It is privacy infringement, but the advertisement world is so big and getting uglier day by day. I guess some day a sensor somewhere on the wall, will pick up words from a normal conversation and you get calls for the bean bags! :(
Yaseen Lanka True that, but isn't it very similar to how Facebook apps work too. They take permission from you for gaining access to your profile details and friends' list etc. Google too tracks almost every movement you make/search you make effectively to gain important user information.
In the case of WhatsApp though, there is no provision of a permission for Facebook to gain access into contacts, and even worse, personal chats!
