i tried to send my freind some money and it wouldnt let me because it said his account was a dupe of mine? but he made his account at his house under his own ip address

You have signed on at his house or vise versa meaning you two are now linked together

also u havnt pervided his name

Doesn't matter if you sign up from different locations. You use the same computer or location to log on, and there you go.

well same thing happened to me and friends but hey we were all on at school so yeah :P

if my friend signs in at my house will they be marked as a dupe forever or just until they sign in again at a different ip?

forever.

im willing to bed hundreds of times it seems like just about every time i look on here there is always a new forum talking about dups
