I know some people who has more than one account. Some of them are buying a new one to get a new account name, some does it because of the support of LFS as I do..
Next time I`ll buy a Voucher and then throw it away.. To each new account you need another email adress than the others.
If it´s illegal to do it in that way? I think they need the money. So I don`t see a problem with it..
