Don’t Accept Every Friend Request
There will be a time when you get a friend request from someone you don’t know. While you might not think much of it, accepting that friend request means you’re giving the other person access to your profile and all your posts.
As a general rule, it’s best not to accept all the requests you get. Beforehand, check their profile to make sure you know them or if they know your friends or family.
If you want to take it one step further, go over your friends or followers list and remove anyone that you don’t know or like. Also, get rid of any fake profiles that don’t have a profile picture or use a fake name. Not only will you keep your profile clean, but you might also get rid of possible scammers.
