Why does Google send out adwords vouchers to people like me only to tell them that their accounts are to old to be able to redeem the voucher?!?!?!?

Why bother sending it in the first place if I can redeem it……well you can really but you have to go through the hassle of creating another Google account. I have to say it was worth the hassle as the last voucher I received was £75.

I just dont see what account age has to do with it, especially when I can simply work around that by creating a new account. If Google are resigned to giving me £75 worth of advertising (thanks by the way) then just let me redeem it on my usual account.
