Existing contacts visible in WhatsApp can be blocked to restrict receiving any messages from them.
Thankfully, WhatsApp has a mechanism to block and manage blocked contacts from the app itself. What if you wish to block someone who has suddenly started sending obnoxiously long messages, images, videos and audio? Follow this simple method to block such folks temporarily or permanently.
Open WhatsApp and go to the Settings menu.
Select the Contacts option in the Settings menu.
Select the option - Blocked Contacts.
Tap on the Contact icon on the top right to add more contacts to this Blocked list. To unblock a contact, simply tap on the user's name and select Unblock contact name.
