Enabling member approval mode on Facebook groups helps limit fake and spam accounts. Below is the most detailed method to activate member approval mode on Facebook.

1. How to Enable Member Approval Feature on Facebook Groups
Enabling the member approval feature on groups allows you to check the quality of incoming requests and avoid post spamming within the group. However, enabling this feature will add extra pressure on the Admins as they will have to manually confirm members.
Note: Group management is currently only available on the Facebook Web platform with full editing, approval, and detailed group settings features. The mobile version of Facebook cannot create groups.
Step 1: Open the group you want to enable member approval for and select Group Settings.

Step 2: Next, go to Member Management and select Edit Who Can Approve Member Requests.

Step 3: Then, switch to Admins and Moderators Only mode.

When you switch to the 'Admins and Moderators Only' mode, individuals requesting to join the group will require approval from the Group Admin. This action helps you tightly manage members and prevent fake accounts with malicious intents.
With that, you have completed enabling member approval mode on Facebook groups.

2. How to Approve Members in Facebook Groups as an Admin/ Moderator
Highly privileged accounts in Facebook groups can approve all joining requests. Additionally, admins/ moderators have the authority to remove members when necessary.
Step 1: Access the Facebook group with your admin account. Then, navigate to the Member Requests section for management.

Step 2: Here, you'll find all the joining requests from members. You can review the summary information on the member's profile page and make a decision to Approve or Decline.

By doing this, you can effectively control group members and efficiently filter out new ones.
