Fighting Spam in Whatsapp
Whatsapp know about the above privacy threat but somehow they don’t change the options in such a way as it could badly affect the active users base, but they have provided several option to block or stop receiving spam messages from some bot or even from someone in or outside your contact list.
Block Whatsapp Spam Number
The first type of blocking is there in whatsapp which allows you to directly block a person, as for these messages which are normally being sent from some computer bot or some other way have the option to get blocked directly. (As you can see in the screenshot below)
Once you tap on the block button on the top left you will get the option to confirm
Now tapping red block option at the bottom you will see that the contact will be blocked and you will not receive message from this number from now on, but if you change your mind you can revert it back as you will see the option to unlock this number as well.
Note: Above method has been done on iPhone 5 running whatsapp with iOS 7.1 but same way you can use this method on other smartphones as well.
