Wondering why the Add Friend button, which sends a friend request when clicked on it, does not appear on the few profiles who you wish to connect with?
Well, there is absolutely nothing wrong with your account at all! In general, any online account, such as a bank, shopping, can be customized through settings. Facebook is no different and allows one to change their profile settings as per one’s preferences. Hence the appearance of the button depends on the profile settings and the limitations of Facebook.
The known possibilities for the button’s disappearance are:
• The profile has changed settings such that people can't add them as a friend. The only way to connect is to ask them to add you if they know you.
• When you don’t have any friend in common, the button will not appear. You have to add a friend who already exists in their friend list to be able to send a request to them.
• Facebook limits the amount of friends per profile can have. Therefore, if their profile exceeds this limitation any more friend requests cannot be accepted. And, they cannot send a friend request to you as well; to do that, they will have to remove some people from their existing friend list.
• Facebook has “spam” feature that avoids unknown people from sending friend requests again and again. In this case, only they are able to send a friend request to you and unless they un-spam your profile you would not be able to send a friend request.
If you doubt that any of the above possibilities might not be the case or believe that there actually exists an issue within your profile, contact Facebook customer support for more information.
