Yeah, I do - that's how I met my wife! several years ago, she was the first person who added me on QQ. She was about to leave High School and go to College, and she added me to practice her English.

Second person was married, and wanted foreign friends. Third girl was married, and wanted black men (no joke, she probably missed crimo). Some of them said they were party officials who wanted to learn more about me, or I ran into one randomly here and there.

I ran into several batshat insane people via random QQ invites, so I stopped allowing people to find me. It got really bad when I had a psycho stalker adding me constantly under new names, and bothering me every single day... so I got a new account (twice) and re-added my "realish" friends. I lost the password to the first account, but kept it logged in... then I re-added my wife to the new account. Wow... could've lost her forever. That was really close...

Yeah, I talk to them, but not anymore. Married now.

Did you post your QQ number on some random forum or something?  I occasionally get a random request but I don't accept them anymore.  Everyone is a scammer trying to get money from you.   

There are days when several guys will try to add me on qq. Half the time I allow it, but end up blocking them because they just want to use the webcam and end up asking me stupid questions. So far I have not made any friends with random people on qq.

free camshow after im married, great another bad china day, have 2000 students on my qq, dont remember all of them, but im suppose to.

I've never added any randoms on QQ.  Closest would be random encounters with people face to face, who would then want to be friends, add my QQ, phone number etc.  I'd just give them  my QQ number, and not my phone number.  This way, as soon as they showed any signs of crazy, they got deleted.  Impossible to block phone calls on my cheapo China phone.

wtf i mainly get prostitutes and tea peddlers

no....but I do get the tea peddlers like crimo

I get about 5 or 6 friend requests a week, I refuse all with a simple reply, "Sorry, but I don't think I know you." All my students, friends and colleagues are warned if they want to add me put a message in the friend request telling me who they are.

Friends of friends usually add me because they are curious about me. I also tried chat groups, they aren't fun.

Silly teddy last user name Daben NO! WHy would there be a need to talk to random people on QQ? You must have a lot of free time, and I do mean a lot! You should go out and make some friends. 

when you are online your number and profile appear to be avialable for random people to contact, and for you to accept or reject as you wish.

I block all QQ requests as i got a few from random Chinese guys who want to video chat and expose themselves to me.

i ask for my friends QQ number and contact them rather than vice versa.
