Facebook已成为最知名的社交媒体网站之一，目前拥有最多的用户。很多吸引力在于能够添加可以关注并查看您发布的内容的朋友，反之亦然。因此，您可能遇到过添加某人的情况，但是添加某人的选项却神秘地消失了。
您无法在Facebook 上(Facebook)添加某人的原因有很多，但这并不意味着有人自动屏蔽了您。如果您想知道其中一些其他原因可能是什么，请查看下面的列表以找出可能发生在您身上的原因。
1.他们的隐私设置 (Their Privacy Settings )
您可能无法在Facebook 上(Facebook)添加某人的一个常见原因是他们可能更改了隐私设置(privacy settings)。Facebook 的隐私设置中有一些选项无法让您添加某人。如果此人的好友请求(Request)隐私设置为“好友之友”，而您没有共同好友，您可能无法向他们发送请求。
如果您仍想向他们发送请求，您可以向他们发送消息并要求他们向您发送请求。请注意，由于您不是朋友，因此您的消息将出现在此人的消息请求页面中。因此，他们可能需要一段时间才能真正看到您的信息。
2.账号被停用(The Account Is Deactivated)
如果某人的帐户已被停用，您也可能无法添加某人。当有人这样做时，他们的帐户通常会以某种形式保持不变，除非他们完全删除它(deleted it)。但是，只要他们的帐户被停用，任何人都无法向他们发送好友请求。
如果有人在停用其帐户后决定登录Facebook，它将再次出现。当他们的帐户被停用时，他们仍然可以使用Messenger，因此如果您想向他们发送消息，您仍然可以这样做。
3.你被屏蔽了(You Have Been Blocked)
在 Facebook 上，一个人可以阻止其他(block someone)人查看他们的个人资料或以任何方式与他们互动。除了看不到他们的个人资料外，您也看不到他们的帖子、照片、评论，也无法给他们发消息。您可以通过尝试向他们发送消息来查看是否有人阻止了您。如果您根本无法向他们发送消息，则您可能已被阻止。
4.你屏蔽了他们(You Blocked Them)
如果您尝试添加某人但似乎无法访问他们的个人资料，您可能想看看这是否是因为您实际上阻止了他们(blocked them)。如果您这样做已经有一段时间了，那么您完全有可能忘记了。
您可以检查您已阻止的人，因为Facebook保留了阻止列表。要查看此内容，请转到“设置和隐私(Settings & Privacy )” > “设置”( Settings ) > “阻止( Blocking)” 。在此页面上，您应该会看到您已阻止的人的列表，并且您可以检查您要添加的人是否在那里。要解除对他们的阻止，只需选择他们姓名旁边 的解除阻止按钮。(Unblock)
5.他们已经达到了他们的朋友限制(They Have Reached Their Friend Limit)
实际上，您可以在Facebook 上拥有(Facebook)多少朋友(how many friends)是有上限的。如果某人已达到此 5000 个好友的限制，您将无法再向他们发送好友请求。如果您尝试这样做，Facebook应该会通知您此人已达到 5000 个朋友。
如果达到限制的人向您发送好友请求，您仍然无法通过这种方式添加他们。如果您尝试接受请求，Facebook不会将他们添加到您的好友列表或您添加到他们的好友列表中。但是，您当然仍然可以向拥有 5000 位或更多朋友的任何人发送消息。
6.你已经发送了请求(You Already Sent a Request)
您可能需要检查您是否已经向某人发送了请求，因为这将删除添加此人的选项，直到他们接受请求。如果您发送请求已经有一段时间了，但他们仍然没有添加您，那么很容易忘记它。
如果您想提醒某人您已发送请求或要求他们添加您，您仍然应该能够向他们发送消息。他们可能忘记了该请求，或者该请求在此人收到的其他朋友请求中丢失了。
7.他们拒绝了你的请求(They Denied Your Request)
另一种可能性是该人已经拒绝了您的请求。如果您已经发送了请求并且不确定为什么仍然看到“添加好友”(Add Friend)按钮，最可能的原因是他们拒绝了您的好友请求。如果您愿意，您可以尝试发送另一个请求，只要“添加朋友”(Add Friend)按钮仍然存在。
此外，如果他们已经向您发送了好友请求而您拒绝了，但您现在想要添加他们，如果他们有某些隐私设置，您可能看不到添加好友按钮。(Add Friend)他们将不得不再次向您发送好友请求。
8. Facebook 限制了他们的账户(Facebook Restricted Their Account)
有时，如果有人向Facebook举报了足够多的次数，或者发现他们违反了Facebook准则，他们实际上会在一段时间内限制此人的帐户。时间段可以从几小时到几周不等。在此期间，将不再允许此人进行特定活动。
这可能是您无法添加人员的原因。您可以尝试等待一段时间，然后再回来查看是否可以这样做。有时Facebook也可能限制此人使用Messenger的能力，因此您也可能无法通过这种方式联系他们。
在 Facebook 上添加朋友(Adding Friends on Facebook)
由于Facebook的重点之一是添加他人并与他人互动，因此当您遇到麻烦时可能会感到沮丧。如果您发现您尝试添加的每个人都出现此问题，或者您在添加人员时遇到错误并且无法弄清楚原因，您可以随时尝试联系Facebook支持以查看是否还有其他问题。
希望(Hopefully)您通过这些原因之一找到答案，并可以继续与朋友互动并享受社交媒体平台。
Why Can’t I Add Someone on Facebook? 8 Possible Reasons
Facebook has become one of the most well-known social media ѕites, and currently has the most users among them. A lot of the aрpeal is being able tо add friends who can follow and see what you post and vice-versa. So you may have сome across the situation where you go to add someone, but the option to do so has mysteriously disappeared.
There are many reasons you can’t add someone on Facebook, and it doesn’t automatically mean someone has blocked you. If you’re wondering what some of these other reasons may be, look at the list below to find out which one may be occurring for you.
1. Their Privacy Settings
A common reason you may be unable to add someone on Facebook is because of how they may have changed their privacy settings. There are a few options on Facebook’s privacy settings that could not let you add someone. If this person has their Friend Request privacy set to “Friends of Friends,” and you have no mutual friends, you probably won’t be able to send them a request.
If you still want to send them a request, you can message them and ask them to send a request to you. Just be aware that since you aren’t friends, your message will land in the person’s message requests page. So it might be a while before they actually see your message.
2. The Account Is Deactivated
You may also not be able to add someone if their account has been deactivated. When someone does this, usually their account will stay up in some form unless they completely deleted it. However, no one will be able to send friend requests to them as long as their account is deactivated.
If someone decides to log in to Facebook after deactivating their account, it will show up again. They can also still use Messenger while their account is deactivated, so if you wish to send them messages, you can still do this.
3. You Have Been Blocked
On Facebook, a person can block someone else from viewing their profile or interacting with them in any way. Besides being unable to see their profile, you also cannot see their posts, photos, comments, and won’t be able to message them. You can see if someone has blocked you by trying to message them. If you’re not able to message them at all, you’ve likely been blocked.
4. You Blocked Them
If you’re trying to add someone but can’t seem to access their profile, you might want to see if this is because you actually blocked them. If it’s been a while since you did this it’s entirely possible you forgot.
You can check who you’ve blocked as Facebook keeps a block list. To see this, go to Settings & Privacy > Settings > Blocking. On this page you should see a list of people you have blocked, and you can check to see if the person you’re trying to add is there. To unblock them, simply select the Unblock button beside their name.
5. They Have Reached Their Friend Limit
There is actually a cap to how many friends you can have on Facebook. If someone has reached this 5000 friends limit, you will no longer be able to send them a friend request. If you try to, Facebook should notify you that the person has reached 5000 friends.
If someone who has reached the limit sends you a friend request, you still won’t be able to add them this way. If you try to accept the request, Facebook will not add them to your friend list or you to theirs. However, you can certainly still message anyone who has 5000 friends or over.
6. You Already Sent a Request
It’s possible you may want to check if you’ve already sent a request to someone, as this will remove the option to add the person until they accept the request. If it’s been awhile since you’ve sent the request and they still haven’t added you, it’s easy to forget about it.
If you want to remind someone you’ve sent a request or ask them to add you, you should still be able to send them a message. It’s possible they’ve forgotten about the request or it got lost among other friend requests the person has received.
7. They Denied Your Request
Another possibility is that the person has already denied your request. If you already sent a request and are unsure why you still see the Add Friend button, the most likely reason is that they denied your friend request. You can try sending another request if you wish, as long as the Add Friend button is still there.
Also, if they sent you a friend request already and you denied it, but you now want to add them, you may not see the Add Friend button if they have certain privacy settings. They will have to send you a friend request again.
8. Facebook Restricted Their Account
Sometimes, if someone is reported to Facebook enough times or they’re found to be going against the Facebook guidelines, they will actually restrict the person’s account for a certain time period. The time periods can be anywhere from a few hours to weeks. During this time, the person will no longer be allowed to do specific activities.
This could be the reason you’re unable to add a person. You can try to wait awhile and then check back to see if you’re able to do so then. Sometimes Facebook may also restrict the person’s ability to use Messenger, so you may be unable to contact them this way as well.
Adding Friends on Facebook
Since one of the main points of Facebook is adding and interacting with others, it can be frustrating when you run into trouble doing this. If you notice this issue is occurring with everyone you try to add, or you’re having errors adding people and can’t figure out why, you can always try to contact Facebook support to see if there’s something else wrong.
Hopefully you find your answer through one of these reasons, and can continue to interact with friends and enjoy the social media platform.
