How to Block Anyone from a Facebook Group (even if they aren’t in it)

Have a Facebook group and need to block someone, but they aren’t actually a member of the group? Here’s how to block anyone from a Facebook Group, even if they aren’t in it!

Hey y’all, Tiffany here.

This post is really different from what I usually right, but I felt like this was really important for anyone who is an admin of a Facebook group, especially a public group.

As you may know, I have an Amazon deals group that I kept from back when I was a coupon blogger.

Lately, it seems like the group has been flooded with spammers. Usually I just block them from the Facebook group. But these spammers reply to comments for people to join their own group, then leave so they can’t be blocked and have all of their comments deleted at once.

We also have issues with people who are admins of other deals groups stealing our deals – sometimes they copy and paste word-for-word! Amazon requires deals groups to be public groups, so people see all of the posts whether they are members or not.

Unfortunately, it isn’t easy to block people who aren’t actually members of the group. Facebook doesn’t have anything in their Help Center about it.

I did some digging, and I was finally able to come up with how to block anyone from a Facebook group, even if they aren’t a member!

How to Block Non-Members from a Facebook Group

Please note that this trick to block non-members from a Facebook group only works for administrators of a group. Moderators will not be able to do this.

Step 1 – Group ID

Find your group ID number. You can find it in the URL of your group:

block facebook group

Step 2 – Profile ID

Find the ID number of the person you want to block from your Facebook group. You find this by going to their profile and looking at their URL:

block facebook group nonmember

Some don’t have a number on the end, like this one below. If that happens, you can find that user ID here.

block facebook group who isn't a member

Copy and paste this link below. You must leave it in mobile format (with the m. in the front) for it to work. You can do this on a desktop or a phone, however.

Replace the 11111111 with your group ID number, and the 2222222 with the profile ID number.

Step 4 – Block them!

Copy and paste the URL you created with the numbers into your browser. You should then get a screen asking you if you want to block them from your Facebook group.

(If you removed the m. at hte beginning, you will get a broken link screen instead.)

Click “Confirm.” Now, the screen may load for a minute, but then it will go back to the same look. It will not actually change from this view with a confirmation, but it should have worked. (I click confirm about 5 times for good measure.)

You can double-check by going back to your group and seeing the Blocked Members.

You’ve Done a Facebook Group Block!

Congratulations! You’ve now blocked someone from your Facebook group who isn’t actually a member of the group!

Hopefully this post will help you with your own Facebook groups in the future.

  1. Thank you it worked. I didn’t know what browser you meant. I just tried putting the URL everywhere 😂 not sure which one exactly blocked them but their activity is gone. Hoping you can explain exactly where you’re talking about pasting the link in the browser

      1. I can’t get it to work for me. It says the link may be broken or the page removed. Help!

        1. I was just barely able to reproduce it, so you must be copying the group number and/or the person’s ID number incorrectly. If you email me at [email protected], I can help a little more.

  2. Works for me! Thankfully it blocks those pesky dumbasses who have a hard time letting go/getting the boot. Thank you for saving me from more aggravation!
