If you’re sending someone WhatsApp messages, but you’re not getting any replies, you might be wondering if you’ve been blocked. Well, WhatsApp doesn’t come outright and say it, but there are a couple of ways to figure it out.
如果您要向某人发送WhatsApp消息，但没有得到任何答复，则您可能想知道是否已被阻止。 好吧，WhatsApp不能一口气说出来，但是有两种方法可以解决它。
在聊天中查看联系方式 (See Contact Details in Chat)
The first thing you should do is open a conversation in the WhatsApp application for iPhone or Android and then look at the contact details at the top. If you can’t see their profile picture and their last seen, it’s possible that they have blocked you.
您应该做的第一件事是在适用于iPhone或Android的WhatsApp应用程序中打开一个对话，然后查看顶部的联系方式。 如果您看不到他们的个人资料照片和他们最后一次看到的照片，则可能是他们阻止了您。
The lack of an avatar and last seen message isn’t a guarantee that they’ve blocked you. Your contact could have just disabled their Last Seen activity.
缺少头像和最后一次看到的消息并不能保证他们阻止了您。 您的联系人可能刚刚禁用了他们的“最近一次”活动 。
尝试发短信或打电话 (Try Texting or Calling)
When you send a message to somehow who has blocked you, the delivery receipt will only show one checkmark. Your messages won’t actually reach the contact’s WhatsApp.
当您以某种方式向阻止您的人发送邮件时，收据将仅显示一个选中标记。 您的消息实际上不会到达联系人的WhatsApp。
If you messaged them before they blocked you, you would see two blue checkmarks instead.
如果您在他们阻止您之前向他们发送了消息，则会看到两个蓝色的选中标记。
You can also try calling them. If your call doesn’t go through, it means you might have been blocked. WhatsApp will actually place the call for you, and you’ll hear it ring, but no one will pick up on the other end.
您也可以尝试致电给他们。 如果您的电话未接通，则表明您可能已被阻止。 WhatsApp实际上会为您拨打电话，您会听到铃声响起，但另一端没有人接听。
尝试将它们添加到组中 (Try Adding Them to a Group)
This step will give you the surest sign. Try to create a new group in WhatsApp and include the contact in the group. If WhatsApp tells you that the app couldn’t add the person to the group, it means that they have blocked you.
此步骤将给您最可靠的信号。 尝试在WhatsApp中创建一个新组，并将联系人包括在该组中。 如果WhatsApp告诉您该应用无法将该人添加到群组中，则表明他们已阻止了您。
If you’re annoyed, you can block someone back on WhatsApp quite easily.
如果您感到恼火，可以很轻松地阻止某人返回WhatsApp 。
