Blocking Someone on Facebook Messenger
In this case, they will know you've blocked them because they will be unable to message you at all or even see your Facebook profile.
You don't see a contact's new profile picture
If someone blocks you and then changes their profile picture, you won't see the new profile picture — you'll always see whatever the image was when you got blocked.
Limited Visibility. In some cases, even if you're blocked by someone, you may still be able to see their comments or likes on other public accounts. However, you won't be able to interact with their content or view their profile directly.
When you block someone's Facebook profile on Messenger, it also blocks their profile on Facebook. They won't be able to message, call or find your Facebook profile. If you're Facebook friends, blocking them also unfriends them. Profiles won't be notified when you block them.
If you see a warning saying that the message wasn't sent, the person might have blocked you. If you can view the person's Facebook profile, they may have blocked you on Messenger but not on Facebook.
Instead of blocking a person, you can restrict them. This means the conversation is moved from your chat list and they can't see when you're active.
No. When you block someone on Facebook and if they search for your profile on Facebook, you will not appear in Facebook search results. Similarly, if you search for the blocked person, they will not appear in your search results.
A filled-in blue circle next to your message means that your message was delivered. And, when a friend has read your message, a small version of your friend's photo will appear next to your message. Jessica Mercado and 20,027 others like this.
You might see "This person is unavailable on Messenger" if you can't Facebook message someone. If your friend has deactivated their Facebook account, you won't be able to send messages to them. If you've been blocked by someone, Facebook messages won't go through to them.
Duration of a Temporary Block
It has been observed that a temporary block may last as little as a few hours, but could also last up to 30 days.
You could, for example, write “Anonymous” or “Secret” as the sender. It does not matter if you've been blocked on Facebook Messenger or anywhere else. A text with an anonymous sender will always be delivered.

A padlock icon is displayed next to the person's profile picture to tell you if a conversation is 'Secret'.
If there is no green dot next to their name, they are either offline or have not logged into Messenger recently. You can also tell if someone is on Messenger by looking at the time stamp next to their name. If you see a time stamp that says 'active now,' it means they are currently online.
A filled blue circle with a checkmark means that your message has been successfully delivered to the other person. While you cannot ensure that the person has seen the message, you can ensure that it has made it to their device.
When you ignore a conversation, you won't be notified when the person messages you directly, and the conversation will move to your connection requests. When you ignore a conversation, the person won't be notified.
If you don't see next to a person's name, it means they have turned off their Active Status feature in their settings. When your Active Status is turned on, you'll appear active or recently active time on this profile.
If the person in question is a Facebook user, head to their profile to see if they have been active recently. If their profile indicates that they are logged in, they've likely blocked you on Messenger.
Profiles won't be notified when you block them.
MacDonald tells us that deactivated accounts' profiles and profile photos “will still be visible on your friend's list, although you can't click on them anymore. Someone who has blocked you won't show up at all.”
To do this, you must log in to your Facebook account and click 'Friends' to navigate your friends list. After that, tap on 'All Friends' and search for their name by typing them in the search box. If their name shows up, you're okay; if not, that is a sign that you might have been blocked.
