Too many captchas to solve. I know this is to prevent bots and other improper use, but do you know when you solve too many Google Recaptcha in a day?
I think you should replace with other service like Solve Media.
Few pages behind in this topic someone posted a hint how to skip a mellow ads (any short link) redirect after solving a captcha, you will have to click somewhere on empty area page of the shrink link after load to activate the popup ,on this way you will solve only 1 time captcha .
