How to set Momo not to accept private messages?

When chatting, you don't want to read the information sent by the other party. You can set not to read other people's information in the settings.

Don't accept each other's information, if you think you are in a stranger. If I introduce other people's information, you can remember it. Accept the bone, or you can delete it. But if you don't want to delete it and don't want to be disturbed, just select the information and don't disturb it. No matter what message he sends you, you can read it if you want, or go without reading it if you don't want to. I think this is a normal phenomenon.
