I was just thinking of a method for free Bing Ads which I am pretty sure is illegal and but I am surprised I never saw this anywhere: 1. Create a new Bing Ads account and add a PayPal account as your payment method. 2. This will make it PostPay up to $50 and once you run a campaign and your balance gets to $45-$49 you go to your PayPal account and cancel your Microsoft agreement in your preapproved payments so they can't charge you. Just making sure this is illegal and stupid right? I just can't believe no one has posted this anywhere on the internet (or at least I can't find it).
