What do they see when you block someone on WhatsApp
When you block someone on WhatsApp, they will not be able to see your online status or when you were last active on the app. They also won't receive any new messages or calls from you, and any previous messages you sent to them will not be delivered.
When they try to send you a message, it will appear to them as if the message has been sent, but they won't receive a delivery confirmation. They will also not be able to see your profile picture or status updates.
Additionally, if you were previously in a group chat with the person you blocked, they will not be able to see your messages in the group chat or mention your name. However, they will still be able to see that the group exists and who the other members are.
It's important to note that blocking someone on WhatsApp is a one-way action, meaning you will also not be able to see their online status, messages, or calls.
