How does Super QQ blacklist friends and send short messages?

Please send the message "n, QQ number" to10661700159 (such as n, 123456) to block this friend's message, or directly reply "n" after receiving his friend's message, and his message will not be sent to you.

Tips: If you need to remove the restriction on this friend's message, you can edit the short message "Y, QQ number" (such as Y, 123456) and send it to1061700159.
