Whether you can see when a blocked contact is online depends on the platform you are using. On most social media sites and messaging apps, blocking someone prevents them from viewing your profile and prevents you from viewing theirs. However, there are a few exceptions.
On Facebook, blocking someone prevents them from seeing your profile, posting on your Timeline, starting conversations with you, adding you as a friend, inviting you to events or groups, tagging you in photos, or seeing things you post on friends’ Timelines. However, they can still see your comments on mutual friends’ posts.
When you block someone on Facebook:
- They can’t see your Facebook profile.
- Your name is removed from their friends list.
- You disappear from their chat contacts list.
- Conversations with you are removed from their inbox.
- Any friend requests between you are canceled.
- They can’t start a conversation with you.
- They can’t add you as a friend.
So in summary, when you block someone on Facebook, you also won’t be able to see their profile or see when they are online.
Blocking someone on Instagram prevents them from:
- Viewing your profile, posts or stories

Conclusion
In summary, on most major social media platforms and messaging apps, blocking someone prevents both you and them from viewing each other’s profiles and online/activity status. The main exception is WhatsApp, where blocked contacts can still see limited profile information like your profile photo and online indicator.
So in most cases, when you block someone, they won’t be able to see if you’re online. And you won’t be able to see if they are online either. Blocking eliminates contact in both directions in order to prevent harassment or unwanted interactions.
