If someone is bothering you with unwanted messages, WhatsApp provides the option to block that particular individual from the Chats screen and anyone bothering with unwanted calls can be blocked from the Calls screen in WhatsApp.
While blocking anyone that is bothering you with unwanted calls or messages on WhatsApp is easy and does not require a second, blocking a known person often leads most people to think about the after effects of blocking someone on WhatsApp – What exactly happens when a person is blocked on WhatsApp?
What Happens When You Block Someone on WhatsApp?
Here is a summary of what exactly happens when you block an Individual or Group Contact on WhatsApp.
1. WhatsApp does not send a notification when you block anyone. Hence, the blocked person won’t be able to know about being blocked by you in WhatsApp.
2. Blocked person won’t be able to see your WhatsApp Last Seen information, Profile picture changes and Status updates.
3. Messages sent by the blocked person will not show up on your mobile device; as they will no longer be delivered by WhatsApp to your mobile device.
4. Blocking someone in WhatsApp will not remove the blocked person from your Contacts list, nor will it remove you from the Contact List of the person that you are blocking.
5. The blocked person might be able to guess about being blocked by noticing the following signs.
- They are unable to see your ‘WhatsApp Last Seen’ or any other activity online.
- They begin to notice that sent messages (to you) are showing up with one check mark and the second check mark (message delivered) is missing.
- WhatsApp Calls to your number are not going through.
Once you have clearly understood the impact of blocking someone in WhatsApp, you can go ahead and use any of the following methods to block the person that you wanted to block on WhatsApp.
