You know I never heard about QQ even considernig that I visited China couple times. According to your desription it reminds me ICQ)) but I understand that it can be wrong)) Maybe it reminded me ICQ coz you shared this story how you gifted you QQ account to your mate. I had similar case with ICQ when my friend gave me his number and said now it's yours and you can use it)) Ohh it was old good times!!!
Also this situation with approving that it's your account reminds me what is happening now here and authorities tries to connect all what just possible to local app called max...
Also I want to mention about @cutehive site, noticed that now I can't it oppen whitout additional "tools" coz seems some providers try to block it. Have you fought about creation mobile app as a one of methods to pass this block and bans? I mentioned mobile app coz on example of ecency app it works good but on site I can get just with additional wlesstools also as on cutehive now.
