Usually it's the underage kids that keep making accounts. Otherwise, I see no reason to make more than one account. With the exception of people who use "Anonymous" all the time. As far as I know, no one has more than one account. Why would someone want more than one?
I've made more than one account on sites because I've forgotten my password lol but on here, I def. Won't have that problem, I've gotten smart. Maybe some people are forgetful like me xD haha just a thought, I'm trying to be positive lol
I had a friend who did that because she has a multiple personality disorder..
