I am a premium member and my rolls have a CAPTCHA also. It is Cloudflare’s CAPTCHA and the checkbox is automatically ticked for me when I visit the faucet page. It is not too bad of a situation if you don’t have to click on it, but depending on users’ privacy settings it might cause problems for some people. I know sometimes people have trouble accessing Bitcointalk because Cloudflare won’t verify they are human.
