When you block someone on WhatsApp, several things happen:
- You will no longer receive messages, calls, and status updates from the blocked contact.
- The blocked contact wont be able to see your "last seen" timestamp, status updates, and profile picture changes.
- Messages, calls, and status updates sent by the blocked contact wont show up on your phone and won’t be delivered to you.
- The blocked contact wont be notified that they have been blocked.
- Blocking a contact wont remove them from your contacts list, nor will it remove you from the list on the contacts phone.
- The blocked contact can still see your messages in a group you both participate in, and youll see their messages in that group as well.
- You can unblock someone youve blocked at any time.
In summary, blocking someone on WhatsApp prevents direct contact from that user, but it doesnt remove them from your contacts. Its a way to cease contact without having an uncomfortable confrontation, and the blocked contact wont be notified of the block.
