Qq Yellow Diamond: Why do you want to talk about traces?

There is no privilege to use yellow diamonds or no self-deletion.

QQ yellow diamond will leave a trace, but you can set the browsing without a trace, or you can delete the browsing record manually, and if the other party sets the browsing record to be visible only to yourself, you can't delete it manually.

QQ yellow diamond can send private messages. The message content in the friend space can only be seen by the owner and Huang Diamond himself. Private comments, as well as comments in friends' news, can only be seen by the owner and Huang Diamond himself. Check for blocked visitors. When non-friends visit your space, they are blocked by your space settings and can only be used after opening the yellow diamond.
