You need to change your Captcha provider immediately, if you expect to have any traffic from fauceters. Most of us fauceters visit dozens, if not hundreds, of sites a day, and are required to fill out captchas on all of them. So when we get a reCaptcha 1 as the captcha challenge, there is no way we can get it right. This is what we see:

I wouldn't say you're missing out on much.
And you do realize that your website claims that you've paid out $5,025,004.48 in earnings. That's quite phenomenal for a new site.
