Will qq leak information when it joins the group?

No. Although you need to verify the information when you join the qq group, usually only the group owner can get the verification information, thus ensuring the information security and privacy of the members in the group, which shows that there will be no information leakage. At the same time, QQ is certified by the Ministry of Industry and Information Technology, and there will also be professionals on QQ to investigate and deal with illegal acts.
