What is how to block someone on facebook before 48 hours?

As an AI language model, I don’t have the ability to perform any actions, including blocking someone on Facebook. However, here is a general guide on how to block someone on Facebook:

1. Log in to your Facebook account.
2. Go to the profile of the person you want to block.
3. Click on the three vertical dots on the top right corner of their profile.
4. Click “Block” from the drop-down menu.
5. Confirm the action by clicking “Block” again.

Once you have blocked someone on Facebook, they will no longer be able to see your timeline, tag you in posts, or contact you. Note that if you block someone, you won’t be able to see their content, and they will not be notified of your action.

It’s important to remember that once you have blocked someone, you may not be able to unblock them for up to 48 hours. This is because Facebook puts a hold on unblocking to prevent harassment or spamming. Once the 48 hours have passed, you can go to Settings, click on “Blocking,” and then find the profile of the person you blocked. From there, you can click “Unblock” to allow them to see your content again.
