WhatsApp is also an important part of social media, like Facebook, Youtube or instagram, and in very short time period, WhatsApp has made its unique identity in the social media world.
Like the other feature of the social media, you can also connect with people on WhatsApp, through their WhatsApp number, which insures your privacy on chat with the people, I also use WhatsApp App and do a lot of fun to chat with my friends.
But only the negative point of this feature that some users put very vulgar and violent posts on their WhatsApp account, and shares them, and the WhatsApp Community could not take any action against them. While if we post such vulgar or violent on Facebook, the Facebook community deletes itself, but there is nothing such bounding on WhatsApp.
I Agree that we can only see the post of people, whose we have add ouselves sharing on WhatsApp Number with them, but WhatsApp Community should check the shared post first before forward ahead on WhatsApp.
