Hello,
I've built bots for quite a few social media sites like Twitter, Soundcloud and G+
I also have exploited quora's internal mobile API (just for fun :)), I got this well documented and ready to be used
That means I can easily send requests as if they come from mobile users.
The captcha is not a problem, I can use service like deathbycaptcha to solve it without distrubing you.
Let's have a chat and discuss the details.
Best,
Nick.
