Paste the link of a profile you can no longer find. StalkFace builds the links to check it from your account, from the mobile site and from a private window, then shows what each result usually means. You open every link yourself; nothing is sent to Facebook from here.
Facebook never tells you that you were blocked. You can only read it from the signs, and each sign on its own has another possible cause. Put two or three together and the picture gets clear:
Their profile shows "This content isn't available right now" when you are logged in.
Their name no longer comes up when you search for it, while a friend can still find them.
They are gone from your friends list, but mutual friends still have them in theirs.
In Messenger, the chat says you can't reply to this conversation.
The profile opens normally in a private, logged-out window.
If most of that fits, a block is the likely reason. If the profile is gone in the private window too, it is more likely deactivated.
Blocked or deactivated: the difference
A block hides a profile from one account: yours. Everyone else still sees it, and so do logged-out visitors. Deactivation hides the profile from everyone at once. The name drops out of search and the profile link stops working for all.
A deactivated account can come back at any time, exactly as it was. A deleted account has a 30-day grace period and is then gone for good. From the outside, the two look the same, and so does a third, rarer case: an account Facebook disabled itself.
Can you see a profile that blocked you?
Not from your own account. That is what a block does, and no website changes it. Logged out, you still see the public front of the profile: the name, the profile picture, the cover photo and any public posts. The rest stays hidden from you while the block stands.
Getting around a block with another account goes against Facebook's rules on unwanted contact. If you need to reach the person, a mutual friend is the usual way.
How to use the checker above
Paste the profile link, or just the username or the number, and press the button.
Open the first link and note what Facebook shows your account.
Copy the link and open it in a private or incognito window, where you are logged out. Compare the two.
If you pasted a numeric ID, try the ID link too. It still works after a username change.
Match what you saw with the list under the links.
Common questions
How can I tell if someone blocked me on Facebook?
Open their profile while logged in, then the same link in a private window. If your account gets "This content isn't available right now" but the private window shows their name and picture, that points to a block. Facebook never confirms it, so treat it as a strong sign, not proof.
Is there a deactivated Facebook account checker?
Not an official one, but the test is quick. If a profile is unavailable in your session, in a private window and by its numeric ID, the account is deactivated, deleted or disabled. Facebook does not say which of the three it is.
How can I see a Facebook profile that blocked me?
Only its public front, from a logged-out window: the name, profile picture, cover photo and public posts. The rest stays hidden from your account while the block stands, and no site can change that.
Does a deactivated account show up in Facebook search?
No. A deactivated profile drops out of search for everyone until the person comes back. A profile that blocked you drops out of your search only, while other people still find it.
Can someone see that I checked their profile?
No. Opening a profile link, logged in or logged out, sends no notice to anyone. Facebook does not report profile visits.
