Does anybody else find the CAPTCHAs needed to purchase this a little excessive? I'm doing my best to give them my money, but after 10 failed reCAPTCHA attempts I'm tempted to just close the window.
Back when you could get a steam key for any price, people used to spam 1 cent purchases in order to get mass amounts of steam keys. I think this is left over from when that was possible.
I don't recall ever having any issues myself when donating for a Humble Bundle, but I frequently enter the wrong characters on other sites' CAPTCHAs, so I totally understand your frustration.
Actually, I think it's because I'm always (just barely) beating the average: "Orders below the average must authenticate with reCAPTCHA to help cut down on costly abuse." Is this the CAPTCHA you're referring to?
The captcha is a joke. You're paying a dollar or less for the game, so because a third of that goes to charity, and you're not willing to give more, then they just want to make sure that there is a human with a soul at the other end. Because all data says otherwise.
