You can say whatever you want, but this is called FRAUD, so I think the moderators would have to delete this thread.
Reported.
Technically speaking it's not fraud as BlackFist mentioned, it's a bug in the system. If Yahoo isn't smart enough to figure a way around this, then so be it. If you don't want to hop on the wagon, then why bother wrecking it? nobody is getting hurt here.
P.S. Some legit people would find this useful, I know I did. Heck, I even paid for the phone number.
