I have a dilemma. I saw on multiple forums (incl. this one) people selling tons of adwords vouchers. I really can't image where do they get those in batches of 50-100 vouchers worth of 50$ each. However maybe you can explain that to me too, but, my question is this: if I buy from some seller a voucher who has been fraudulently achived before by the seller what could happen worst with my google adwords/adsense account and my website's position in Google search ? I might get banned forever from Google ? I'm just afraid of these hundreds of coupons for sale
