For the no-catpcha, they may have changed the policy to never hide it anymore despite the deposit thing, but I haven't heard of any official confirmation on that regard.

I was told once by an user that one must have deposited more than his free-rolls winning in order to roll captcha free, but I'm currently at a rate of 1.9:1 of deposits:freerolls and 1.33:1 of deposits:(freerolls+referralcommissions) and still getting captcha. That's unfortunate okay, but they're still offering a great service, just saying.
