Why can't fb brush messages?

The message cannot be printed for the following reasons:

The first reason, the problem of account numbers, is that many people run advertising accounts. These numbers were originally illegal, which triggered the system risk control and restricted you from sending messages to strangers, but they never used the mall function and sold it to you.

The second is the problem that the messenger conversation can't be opened. This part is the problem of network speed, especially some users use 9 1 1. From 2 pm to 5 pm, the internet speed is slower than snail, not to mention that messenger can't be opened, and the homepage is difficult to open. You can't do anything if you open the home page for more than 5 seconds. The root cause of triggering risk control is your network problem. You are always disconnected. A global social software will definitely have systematic risk control. Your account will be online and offline. Coupled with your IP changes, how can you not trigger risk control? So again, a stable line is king.

The third is that the account is registered in some systems, and the original registered address is in some remote countries. It's not my intention to say something inconvenient and offend too many technical colleagues. After logging in, you have changed your environment. If you don't follow the advice given by the vendors, I believe some vendors will tell you what to do when you log in. Some people can't wait to send a message to trigger the risk control, and the number is blocked.

The fourth is the big black number. Messenger is posted on the original owner's mobile phone. If you can't open it, the way is to change the agreement and bind the account with a new mailbox. The original owner's mobile phone is offline, so he can't log in again. Not all accounts can do this. Some accounts in Dahei are destined to be blocked because novices don't know how to change them. In the process of change, the original owner will receive a reminder message and change the password during your change.
