Whether someone is notified when you block them on social media or messaging apps depends on the platform. Some sites and apps will alert a user that they have been blocked, while others will simply make the blocker seem unreachable, without indicating why.
If you block someone on Facebook, that person will not get any notification that they have been blocked. From their perspective, they will simply no longer be able to see your profile or posts. If they try to search for you, your profile will not come up in their results. They will also not be able to start a conversation with you or add you as a friend.
The only way the blocked person might realize they have been blocked is if they notice your profile and posts have suddenly disappeared from their view. Even then, Facebook does not make it obvious that a block has occurred. The platform is designed to quietly remove blocked people from your experience, without notifying them.
Much like Facebook, if you block someone on Instagram, that person will not get notified about it. Your profile will simply disappear from their account. They will no longer be able to view your posts or search for your account. If you blocked them from a joint chat, the chat will still appear for them but without your messages.
The only indication to the blocked user is that your profile is suddenly inaccessible. There is no warning message that they have been blocked. However, it may be apparent if you completely vanish from their view without an explanation.
If you block someone on Twitter, they will not receive any notification that you have blocked them. Similar to other platforms, your tweets and profile simply become invisible to the blocked user without any warning. The only change from their perspective is that you seem to have disappeared.
However, Twitter does allow you to mute users instead of fully blocking them. If you mute someone, they will get a notification that you have muted them, indicating you will no longer see their content in your feed and conversations.
If you block someone on WhatsApp, they will immediately know because your profile photo and “last seen” status will disappear from their app. A blocked contact becomes completely invisible. Unlike other platforms, WhatsApp makes it very clear to users that they have been blocked.
In group chats, a blocked person will still be able to see and send messages in the group, but your messages will appear as “You” instead of your name. They will know they have been blocked by a specific person due to your vague identifier in the chat.
Messenger
If you block someone on Facebook Messenger, whether from your contacts or in a group chat, the person will not receive any notification. Your messages will simply disappear from their view. The only indication they may get is that your profile photo vanishes from their contacts list.
Blocking someone on Messenger makes you completely invisible to that person. They will be unaware they are blocked unless they notice conversations with you have abruptly ceased.
Snapchat
On Snapchat, blocking a user removes them from your friends list and makes your Stories invisible to them. However, Snapchat does notify users when they have been blocked. A blocked contact will see a message that they can no longer view your Stories or interact with you on the app.
So unlike other platforms, Snapchat makes it clear to users that they have been blocked. The blocked user will not get any details beyond a general notification that they can no longer see your profile or communicate with you.
Skype
If you block a contact on Skype, they will get a notification that you have blocked them. When they try to search for your profile or start a chat conversation, a message will pop up alerting them that they have been blocked and can no longer message you.
Skype clearly indicates to blocked users that they can no longer interact with you. Beyond this notification, no other details are provided. But the blocked person will definitively know they have lost access to your profile and cannot contact you.
Gmail
Blocking someone in Gmail does not notify the user or indicate in any way that they have been blocked. From their end, your messages will simply be automatically archived or sent to spam as if nothing has changed.

iMessage
There is no direct way to block someone on iMessage. However, you can block their phone number which removes your ability to send and receive iMessages and phone calls with that person. They will not receive any notification that you blocked their number.

Discord

Telegram
Telegram has two options – you can block users so they are unable to contact you, or report their account which limits their ability to contact any other users. In either case, they will get a notification that their access has been restricted.
With a normal block, the person will know specifically that you blocked them. If you report them, they will get a general notice that their account has encountered limitations but won’t know who reported them.
Signal
If you block a contact on Signal, the app does not notify them in any way. You simply become unreachable and invisible from the blocked user’s end. The only indication they may get is if your profile photo disappears from any mutual group chats.
In essence, Signal blocks work secretly and do not reveal to users that they have been barred from contacting you. The block cuts off communication without alerting the blocked party.

Conclusion
In summary, whether a blocked user is notified depends entirely on the platform:
- On Facebook, Instagram, Messenger, Gmail and iMessage, blocks happen secretly without any notice to the blocked user.
- Platforms like WhatsApp, Snapchat, Skype, Discord, Telegram, Zoom, Slack, and Twitter alert users if they have been blocked.
- Other sites like Reddit, LinkedIn, Pinterest, Tinder, and Bumble make blocking invisible so the user has no indication they have been blocked.
The notification policies are designed around each platform’s approach to privacy and communication. In general, the more transparent platforms notify blocked users while apps focused on anonymity block contacts silently without warning.
