JavaScript To Mass Remove Facebook Group Members

Posted October 26, 2016 at 5:08 pm in Internet & Tech

So it turns out to delete a Facebook group it must have no admins, and no members, which seems kinda silly. So I found this JavaScript to Mass Remove Facebook Group Members and tweaked it a bit so it worked, it takes multiple runs to go through a large group – but in the end it got the job done and I could delete the group.

Offical from Facebook:

If you’ve created a group, you can delete the group by removing all its members and then yourself. To delete a group: Go to the group you want to delete and click Members below the cover photo. Click next to each member’s name and select Remove from Group.

How do I delete a group? | Facebook Help Center | Facebook

The below code can help you with that, make sure you edit the excludedFbIds and enter your own Facebook ID so it doesn’t delete you first. You can find it here: https://findmyfbid.com/

It works fine in Firefox, so edit it, then paste in the JavaScript console and run it. It might have errors sometimes and hang or pause, just reload the page and execute it again. I did a fairly big group with a few thousand members and it cleaned them all out eventually.
