Facebook Disable friend suggestions
A Facebook feature asks you to add people you may not necessarily know. We are talking about the possibility of suggestions from Facebook friends. If you want to turn off these suggestions, let's see what you need to do.
In the web version of Facebook for desktops you can turn off friend suggestions from your account settings. To do this, open Facebook if it is not already open and log in to your account.
Once connected, click the down arrow menu icon in the upper right corner. From the drop-down menu, select Settings & Privacy> Settings.
Alternatively, do click here
Click "Notifications" on the left, alternatively click here.
Select "People you may know" in the "Alert Settings" menu.
Facebook gives you recommended friends in a variety of ways. If you want to stop specific friend suggestions (but you don't mind in-app suggestions), click the slider next to the various options listed (including push, email, and SMS notifications).
With this setting turned off, Facebook will no longer suggest other user accounts to add as friends on the Facebook web or Facebook mobile app.
Now if you want to add friends to Facebook, you have to search for them and add them manually.
