Limto I remember when MSN first came out and I was on it pretty young, I can't remember the age. But MSN was like a user-to-user chat. Sort of like Facebook messenger without Facebook and to add people you have to punch in usernames that vary and are unique. I think i might have been around 8 and only added people I had in my class. There wasnt a way to have random people unless you just typed in random attempts at usernames and that's if they're active.
I was gaming online on pc without a mic around then too maybe, but at a internet cafe where we are supervised.
Either way, we're talking like 2004ish when things were much different and the world wasnt as dangerous of a place in my opinion. Now I wouldnt want my kid to be on such things at a later age than I was.
